	All LPV Households With Valid Health Data	LPV Households Without Baseline Child Health Problems	LPV Households With Baseline Child Health Problems	Difference Between Group Means (Health Problem vs. No Health Problem)
Proportion that moved with the program	0.49 (0.01)	0.50 (0.01)	0.38 (0.04)	−0.12c	0.004
Poverty rate in neighborhood of take-up (estimated using intercensal interpolationd), %	10.77 (0.19)	10.57 (0.19)	13.05 (0.83)	2.48c	0.004
Duration-weighted poverty, average %e	31.95 (0.45)	31.60 (0.47)	34.97 (1.48)	3.37f	0.030
Proportion of time spent in neighborhoods with <10% poverty during the study (1994/1997–2002)	0.17 (0.01)	0.18 (0.01)	0.12 (0.02)	−0.06f	0.011

Abbreviations: LPV, low-poverty voucher; SE, standard error.

^a Excludes households missing valid data on child health at baseline. Values are weighted but unadjusted for other baseline covariates.

^b t test for difference between mean values.

^c P < 0.05.

^d Analyses of LPV compliers only.

^e Duration-weighted poverty was an average of poverty percentages experienced across all neighborhoods in which a participant lived during the study, weighted by the proportion of time spent in each particular neighborhood relative to the total amount of time spent in the study.

^f P < 0.01.
