Living arrangements often reflect important quality-of-life indicators for elderly adults. In particular, increased income can prompt changes in household living arrangements for elderly adults. Using a differences-in-differences approach, we examine whether a supplemental income program in Mexico for adults aged 70 and older influenced household size and composition. We compare outcomes at baseline and at six-month follow-up for elderly adults in the treatment group with those in the control group that did not participate in the program. We find that household size increased by 3% in the treatment group relative to the control group. We also find a statistically significant increase in the number of girls aged 6-11 in the household, likely the granddaughters or great-granddaughters of program recipients. Increases in household size were greatest for adults aged 70-79, couples, households receiving two or more supplemental incomes, and households in the top income tercile. Household size did not increase for households of adults aged 80 and older, singles, households with only one supplemental income recipient, and households not in the top income tercile. These results suggest that when older adults have more income, they use part of this income to house their grandchildren.
居住安排通常反映了老年人重要的生活质量指标。特别是，收入的增加可能会促使老年人的家庭居住安排发生变化。本文采用双重差分法，考察了墨西哥一项针对 70 岁及以上成年人的补充收入计划是否影响了家庭规模和构成。我们比较了实验组和对照组老年人在基线和六个月随访时的结果，对照组没有参与该计划。结果发现，实验组的家庭规模相对对照组增加了 3%。我们还发现，家庭中 6-11 岁女孩的数量显著增加，这些女孩可能是计划受益人的孙女或曾孙女。70-79 岁的成年人、夫妻、获得两份或两份以上补充收入的家庭以及收入最高三分之一的家庭的家庭规模增长最大。对于 80 岁及以上的成年人、单身人士、只有一个补充收入受益人的家庭和收入不在最高三分之一的家庭，家庭规模并没有增加。这些结果表明，当老年人有更多的收入时，他们会用部分收入来安置他们的孙子孙女。
