This is one of the funders for a multi-funder project designed to study the impact of housing on children?s healthy development. This project will target the completion of interviews with 1,686 parent, caregiver, or guardian (PCG) respondents, and 2,328 child respondents aged 3-10 in three metropolitan areas (Cleveland OH, Dallas TX, and Seattle WA). We have assumed that half of the participating households (N=843) will come from local housing authority lists (?voucher respondents?) with the remaining half of participating households coming from random screening of households located in selected census blocks (?population respondents?).
