Note: For average income, SD of incomes and 2011 $ – 2002 $, PP1and PP2 are the predicted probabilities at 0.5 standard deviations below and above their means, respectively. For years in bottom quartile, years in top quartile, downward trajectory of $ and upward trajectory of $, PP1and PP2 are the predicted probabilities at 0 and 1, respectively. RR (risk ratio) is PP2 divided by PP1 and RD (risk difference) is the absolute value of PP1 subtract PP2. Each model controls for age in years, immigrant status, marital status and parental education. Person and replicate weights are applied to each model
