The joint demographic and mobility effect $f_2{p}_{2|2}-f_1{p}_{2|1}$	0.541 (0.016)	0.774 (0.026)	0.586 (0.019)	0.541 (0.016)
Bias (ref. model 1.1)	--	0.233	0.045	0.000

Note: Figures in the parentheses are standard errors.

^*The mobility estimates are the same across all the models, because prospective and the retrospective data yield the same results.
