Abstract
Background This study explores socioeconomic differences in acceptability and preferences for policies that aim to reduce socioeconomic health inequalities. The investigated policies range from structural policies, requiring no individual agency, to agentic policies, which depend on the individual agency for behaviour change.
Methods An online, cross-sectional survey was conducted among 1182 participants, stratified by education and representative of Dutch adults (aged 25–65) for age and gender. Across 31 policies, including structural socioeconomic policies, structural housing and neighbourhood policies, structural and agento-structural behavioural policies (facilitating behaviour) and agentic policies (focusing on information provision for behaviour change), acceptability was measured on a 7-point scale, preferences were measured using participants’ top-5 policy choices. Regression analyses examined socioeconomic differences in acceptability and preferences based on education and income, controlling for age, gender, receiving welfare, and employment.
Results People in lower socioeconomic positions were more likely to accept and favour structural socioeconomic policies, whereas those in higher socioeconomic positions were more likely to accept and favour structural housing and neighbourhood, structural and agento-structural behavioural, and agentic policies. Socioeconomic differences were the largest for agentic policies. Overall, 83.3% preferred at least one structural socioeconomic policy, while only 32% preferred an agentic policy. Most preferred was eliminating taxes on fruits and vegetables, (preferred by 41.4%), and least preferred was a campaign promoting healthy nutrition (preferred by 3.9%).
Conclusions These socioeconomic differences in policy support underscore the need for inclusive policymaking processes. Including the perspectives of people in lower socioeconomic positions helps to ensure that their needs are met.

WHAT IS ALREADY KNOWN ON THIS TOPIC
Policies are often created by people from higher socioeconomic groups, but to what extent these policies align with the preferences of lower socioeconomic groups remains unclear.
WHAT THIS STUDY ADDS
There are socioeconomic differences in public support for policies that aim to reduce socioeconomic inequalities in health.
People in lower socioeconomic positions are more likely to support structural socioeconomic policies.
People in higher socioeconomic positions are more likely to support housing and neighbourhood, behavioural and agentic policies.
HOW THIS STUDY MIGHT AFFECT RESEARCH, PRACTICE OR POLICY
Current policies designed to reduce socioeconomic inequalities in health may not align with the preferences of lower socioeconomic groups, who may benefit most from structural socioeconomic policies.
Incorporating the perspectives of people from lower socioeconomic positions during the policy-making process is needed to ensure that their needs and preferences are considered.
Background
Socioeconomic inequalities in health are widening, and it remains challenging to reduce these inequalities.1 2 While underlying causes of health inequalities are increasingly well-understood, there is less agreement on viable solutions.3 A better understanding of the most suitable policy solutions may help reduce socioeconomic inequalities in health.3
Many policies are proposed to reduce socioeconomic inequalities in health,2 each requiring varying levels of individual agency for behaviour change. Following Backholer et al’s4 framework, policies can be divided into structural, agento-structural and agentic policies. Structural policies target the root causes of inequality or poor health and require no individual agency.4 Examples are policies that enhance living conditions.2 Agento-structural and especially agentic policies require the individual agency to improve health. Agento-structural policies aim to structurally encourage healthier behaviour through choice architecture, by for instance removing taxes on fruits and vegetables.4 Agento-structural policies have structural and agentic components. Agentic policies, however, fully depend on individual agency, for example, by providing information on healthy behaviours.4 Agentic policies are considered the least effective in reducing socioeconomic inequalities in health,5 6 while agento-structural and especially structural policies are considered the most effective.7
The understanding of health is socially patterned.8 People in higher subjective socioeconomic positions (SEP) were more likely to consider behavioural explanations for poor health, while people with lower subjective SEPs were more likely to consider structural factors.8 Stronks et al found that when people with a higher SEP were asked to conceptualise health, they considered eating behaviours as the most important. In contrast, people with a lower SEP more frequently emphasised structural factors like affordable nutritious food.9
Socioeconomic differences in understandings of health could translate into socioeconomic differences in policy support.1 8 10–12 Smith et al examined policy support in the UK, where structural policies received more support than agentic policies. However, socioeconomic differences in support were not investigated.13 Socioeconomic differences have been found in politician’s perceptions of policy support; biases towards preferences of high educational classes were found in Sweden,10 Belgium, Canada and Israel.12 The Dutch policy landscape also tends to be more responsive to the needs of those with higher education.11 Whether there are socioeconomic differences in support for different types of structural or agentic policies remains unclear.14 15
This study
This study explores socioeconomic differences in acceptability and preferences of different structural and agentic policies that aim to reduce socioeconomic inequalities and socioeconomic inequalities in health among adults.
To assess acceptability and preferences across policy levels that require varying amounts of individual agency, the framework of Backholer et al 4 was used. Backholer’s structural and agento-structural levels were expanded into three levels to differentiate policies targeting socioeconomic conditions, housing and neighbourhood conditions and behaviour. The policy levels explored are:
Structural policies targeting socioeconomic conditions (hereafter referred to as socioeconomic policies): arrangements that aim to improve income-related, education-related and work-related circumstances. Examples are social welfare policies and protection against precarious employment.
Structural policies targeting housing and neighbourhood conditions (hereafter referred to as housing and neighbourhood policies): arrangements that intervene on physical living conditions. Examples are policies to improve the insulation of social housing and regulations to reduce air or noise pollution.
Structural and agento-structural policies facilitating behaviour (hereafter referred to as behavioural policies): arrangements to facilitate healthy lifestyles by changing the (structural) availability of products or through (agento-structural) choice architecture. Examples are restricting the availability of unhealthy foods and price reductions of healthy foods.
Agentic policies: arrangements that provide information to increase people’s knowledge or skills, but no structural changes in choice architecture are made. Examples are campaigns on healthy eating and healthy cooking lessons.
Methods
Study design
An online, cross-sectional survey was conducted among 1182 participants.
Participant recruitment
Participants were recruited between January and February 2024 by an online panel.16 Inclusion criteria were being between 25 and 65 years old and living in the Netherlands. Sample size calculation (power of 0.8, medium effect size of 0.2, significance level 0.05) determined 394 participants per SEP. Since educational level is the most reliable indicator of SEP in the Netherlands,17 18 the sample was stratified on educational level, while remaining representative of age and gender per educational level.19 85% consented, leading to 1182 participants. Panel members receive payments based on time investment. For this survey, participants received €0.35.
Survey and variables
The survey (see online supplemental additional file 1) was written and visualised using plain language,20 supporting accessibility among people with low literacy.
Supplemental material
Selection of policies
31 policies were selected. An overview of policies per policy level can be found in box 1. Online supplemental additional file 2 provides information on policy selection.

Information campaign discouraging making purchases on credit or in instalments.
Offering consultation hours to provide advice for people starting financial debt.
Financial education initiatives.
Increased local services offering assistance with letters, administration and financial matters.
Policy acceptability and preferences
Acceptability was assessed by asking: ‘How [acceptable] do you find this policy aimed at improving the health of people in socioeconomic insecurity?’, on a 7-point scale ranging from very bad (1) to very good (7). The order of policies was randomised across participants. A mean score was created per policy level (range 1–7), with a higher value indicating higher acceptability.
Preferences were assessed by having participants rank their top-5 preferred policies, following Smith et al.13 The survey only showed policies that the participant rated as at least ‘somewhat acceptable’. If participants rated fewer than five policies acceptable, they ranked a shorter list. Per policy level, a count variable summed how often policies from that level appeared in the top-5, ranging from 0 to 5 (with a score of 5 indicating that the participant preferred only policies from one level).
Socioeconomic position
Socioeconomic differences were assessed using educational and income level. Educational level was operationalised based on the International Standard Classification of Education (ISCED) 2011,21 categorised as lower secondary (ISCED 0–2), upper secondary (ISCED 3–4) or tertiary and higher (ISCED 5–8). Household equivalent income level was measured as the net monthly household income divided by the square root of the number of people living from this income,22 categorised as tertiles. The lowest income tertile included those with household equivalent incomes below €1556, the middle tertile included those with incomes between €1556 and €2200 and the highest tertile included those with incomes above €2200.
Covariates
Participants reported their age and gender (male, female, non-binary/other), both have been associated with policy support.23 We additionally controlled for paid employment (yes or no) and receiving welfare (yes or no). Previous research suggested their relevance towards policy support,24 and both tend to be socially patterned.
Missing data and statistical analyses
Complete data was collected, except for income, since 13.7% of the sample did not report their income. Multiple imputations by fully conditional specification predicted missing incomes. Educational level, age, gender, receiving welfare and paid employment informed imputation. 14 imputed data sets were created. See online supplemental additional file 3 for unimputed model results.
Analyses were conducted in IBM SPSS V.28.0. Separate regression models were run for the outcomes: acceptability and preferences. Each model included educational level and income level, gender, age, being in paid employment and receiving welfare. Policy acceptability outcomes had acceptable skewness (range −0.36 to −0.54) and kurtosis (range 0.02 to 0.32) thus were treated as continuous in linear regression models. The preference outcomes were count scores thus Poisson regression models were used. To assess goodness of fit, R2 values (higher values indicating a better fit) and the Akaike information criterion (lower values indicating improved fit) were calculated.
Results
Participant characteristics
See table 1 for sample characteristics by education. The majority had monthly household equivalent incomes over €1556 per person, this was more common among those with upper secondary or tertiary education. Half (50.7%) were women. All age groups were represented, with the largest age group aged 55–65 (39%). The majority was in paid employment (69%) this was most common among those with tertiary education. A quarter received welfare, which was most common among those with lower secondary education.
Socioeconomic differences in policy acceptability and preferences per policy level
Table 2 presents estimates for policy acceptability (Model 1) and preferences (Model 2) per policy level. People with low monthly incomes considered socioeconomic policies more acceptable than those with high monthly incomes (no educational differences were found). Housing and neighbourhood, behavioural and agentic policies were considered more acceptable by people in tertiary education than by those with lower secondary education, but no differences in monthly income were found.
Model 2 (table 2) shows that people with lower secondary education and low monthly incomes considered socioeconomic policies more preferable than those with tertiary education and high monthly incomes, respectively. No educational or monthly income differences were found in preferences for housing and neighbourhood policies. Behavioural policies were preferred less by those with lower and upper secondary education compared with those with tertiary education, but there were no monthly income differences. Agentic policies were preferred less by people with lower secondary education and low monthly incomes, compared with those with tertiary education and high monthly incomes.
The imputed regression estimates of table 1 were similar to unimputed model results (online supplemental additional file 3). However, several additional socioeconomic effects were identified in the unimputed data. For instance, those with the lowest incomes were less likely to prefer behavioural policies compared with those with high incomes. Only one socioeconomic effect presented in table 2 did not appear in unimputed data: those with the lowest incomes were not less likely to prefer agentic policies compared with those with the highest incomes.
Socioeconomic differences in preferences for specific policies
Overall, 83.3% included at least one socioeconomic policy in their preference top-5, 53.4% included at least one housing and neighbourhood policy, 62.6% included at least one behavioural policy and 32.0% included at least one agentic policy. Table 3 shows how frequently each policy was included in participants’ top-5 and describes socioeconomic differences. Most preferred was the removal of taxes on fruits and vegetables (41.4%), least preferred was an information campaign promoting healthy nutrition (3.9%).
Preferred 1.5 times or more by those with lower secondary education compared with those with tertiary education (see table 3) were: (1) additional funds for people earning a very low incomes or very low social benefits (ratio: 2.5), (2) lower health insurance premiums and deductibles for people with low incomes (ratio: 2.1), (3) free gym or sport club memberships for people with low incomes (ratio: 1.7), (4) allowing people who receive social benefits to earn additional income through work without impacting their eligibility for social benefits (ratio: 1.6) and (5) more car-restricted residential areas (ratio: 1.5).
Preferred 1.5 times or more by those with tertiary education compared with those with lower secondary education were: (1) imposing a tax on added sugar (ratio: 0.2), (2) expanding smoke-free zones to outdoor spaces (ratio: 0.4), (3) increasing local services for administrative assistance (ratio: 0.4), (4) prohibiting the opening of new fast-food restaurants in fast-food-dense areas (ratio: 0.4), (5) free lessons to enhance health (ratio: 0.4), (6) quicker detection of and assistance for people experiencing financial difficulties or starting to accumulate debts (ratio: 0.4), (7) consultation hours for advice for those with starting financial debts (ratio: 0.4), (8) information campaign promoting healthy nutrition (ratio: 0.5), (9) financial education initiatives (ratio: 0.5) and (10) improving the healthiness of prepared meals and pre-packaged foods (ratio: 0.5). Similar preference ratios were found based on monthly income.
Discussion
This study revealed socioeconomic differences in the acceptability and preferences for different types of policies that aim to reduce socioeconomic inequalities in health. Socioeconomic policies were more often accepted and preferred by people with lower SEPs than those with higher SEPs. In contrast, housing and neighbourhood policies, but also behavioural and agentic policies that require a larger amount of individual agency to improve health were perceived as more acceptable and preferable by those with higher SEPs.
To our knowledge, this was the first study to investigate socioeconomic differences in support of policies requiring varying amounts of individual agency. Support for specific policy types has been studied, such as health behaviours,23 25 obesity prevention,26 alcohol,15 sugar-sweetened beverages,27 active transportation28 or mental health.29 People with a higher SEP may show greater overall support for policies than people with a lower SEP.30 Still, similar to Bridger,8 who found socioeconomic differences in beliefs regarding structural versus behavioural causes of poor health, our findings suggest that the least privileged individuals favoured socioeconomic policies over other policies.
This preference likely arises from the large personal benefits they experience from these policies, consistent with a study showing that improving socioeconomic circumstances and associated stressors is important for improving health among the less privileged.31 In contrast, policy support of people in the higher SEPs was lower for socioeconomic policies and higher for behavioural and agentic policies that place more responsibility for health on individuals. Their lower support for socioeconomic policies may result from a lack of experiential knowledge of living with disadvantages.11 32 Similarly, their higher support for agentic policies may arise from their longer education, through which they may overvalue information provision, and overestimate the power of information provision for those with fewer means available to change their lives.33 In contrast to socioeconomic policies, housing and neighbourhood policies received less support from those with lower secondary compared with tertiary education, potentially indicating a larger perceived benefit derived from socioeconomic than housing and neighbourhood policies. Additionally, socioeconomic differences in environmental concerns could play a role. Many housing and neighbourhood policies relate to sustainability, and greater support for sustainability is found among those with tertiary education.34
The ability of policy to meet the needs of disadvantaged populations becomes particularly concerning when considering socioeconomic differences in policy support, along with educational differences in power. The representation of the Dutch policy landscape is suggested to be highly unequal.11 32 People with lower secondary education are under-represented in political offices,32 and less likely to be politically active and vote than people with upper secondary or tertiary education.12
Although both socioeconomic indicators were associated with policy support, educational differences were most prominent. This aligns with other literature, since educational level is the socioeconomic indicator causing most segregation and differences in the Dutch context.17 Monthly household income mainly influenced support for socioeconomic policies, many directly targeting income.
All agentic policies were more preferred by those in higher SEPs than those in lower SEPs. Although many health policies focus on behaviour and agency,13 23 35 36 they may not align with the needs of people with a lower SEP. Behavioural and agentic policies tend to be more effective among those in higher SEPs, who have more resources available to improve their health, likely widening socioeconomic inequalities in health.6
The highest preference overall was found for socioeconomic policies, in line with Wagemans and Peters.33 However, people with lower SEP more often supported these policies than their counterparts and were particularly more likely to prefer additional income support and reduced health insurance costs.
The behavioural policy level includes the most preferred policy overall: removing taxes on fruits and vegetables, also recommended by health experts.37 People with upper or tertiary education supported behavioural policies more than those with lower secondary education. Offering free sports memberships to low-income individuals was the only behavioural policy more often preferred by those in a lower SEP, highlighting a need for affordable sports. Similar to Eykelenboom et al,27 we found large socioeconomic differences in preferences to tax added sugar, those in a higher SEP were five times more likely to prefer this than those in a lower SEP. Although an added sugar tax is considered effective to reduce socioeconomic inequalities in health,37 it would disproportionately increase living costs among those with lower SEP.26
These results had several strengths and limitations. A main strength is the use of plain language, which limited socioeconomic differences in survey understanding. A broad range of policies were included, and not defining the responsible party for implementation prevented bias against specific actors. The stratified sampling ensured sufficient representation of all educational groups, particularly those with lower secondary education, who are often under-represented in survey research.38 This allowed us to assess policy support between educational levels with the required sample sizes based on our power calculation. However, this limited the sample’s representativeness. Although representative of the Dutch population in age and gender according to National Statistics,19 our sample over-represented people with a lower secondary education (33% compared with 20% in the Dutch population).39 This oversampling could have led to a slight over-representations of people without paid work or receiving welfare. Using education and income as measures of SEP allowed us to capture distinct aspects: education captures access to knowledge, skills and networks,40 while monthly household income measures more immediate economic resources. However, this does not fully capture the complexity of socioeconomic experiences. Furthermore, we did not control for health status or specific health behaviours, which likely influenced support for health policies.15 23 However, given the socioeconomic gradient in health outcomes and behaviours, and since these differences are largely beyond personal control, it is essential to take the socioeconomic differences in policy support seriously, regardless of socioeconomic differences in health and behaviours. Given limited budgets, future research could strengthen our results by prioritising policies based on the perspectives of different socioeconomic groups.
This study highlighted socioeconomic differences in acceptability and preferences for policies aimed at reducing socioeconomic health inequalities. Socioeconomic policies received widespread support, particularly among those with a lower SEP, while those with higher SEPs preferred behavioural and agentic policies. Strong preferences for specific policies such as affordable healthcare, sports and increasing the social minimum while decreasing the costs of living among people in lower SEPs, suggest opportunities for implementation or strengthening in the Netherlands. Above all, the socioeconomic differences in policy support underscore the need for inclusive policymaking processes that include the perspectives of people across all SEPs, particularly those in disadvantaged positions.
