  1. HH refers to household. Survey weights used. t tests of mean differences of stayers and attritors are displayed. Differences may stray from true values due to rounding and weighting. Significance levels are denoted as ***p <0.01, **p <0.05, *p <0.1. Variables are displayed for 2009. Stayers participate five years in a row. Attritors participate in 2009 but not in all 5 years
