Understanding its effects on SNAP participation among low-income older adults is important for evaluating how eligibility expansions influence access to nutrition assistance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Research Design and Methods<\/jats:title>\n                    <jats:p>We combined SNAP Quality Control administrative data with Census population-based survey data from 1996 to 2020 to estimate SNAP reach among low-income older adults across states.

Dynamic estimates indicated that BBCE effects emerged gradually following adoption, with larger estimated effects observed in later post-adoption periods. Observed trends exhibited lower relative cross-state variation in SNAP reach than would be expected without BBCE adoption, suggesting that BBCE moderated the widening of geographic disparities, although substantial cross-state heterogeneity remained.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion and Implications<\/jats:title>\n                    <jats:p>Expanding SNAP eligibility through BBCE may improve access to nutrition assistance among low-income older adults. However, persistent geographic variation in SNAP reach suggests that reducing disparities may require not only expanded eligibility but also state-level administrative and institutional supports that
