Families are coded as poor (p) or not poor (n) at each of the three measurement points (child aged 9 months, 3 years and 5 years). The coding takes into account both the timing and duration of poverty, differentiating families who were poor at all three measurement points (ppp) from those who moved into poverty only at the last measurement point (nnp), those who experienced poverty only at the second measurement point (npn) and so on. The reference category is not being poor at any of the three measurement points (nnn).
