In the past decade, a significant shift has emerged around immigration policy, as advocates and policymakers have made various efforts to pass state and local policies related to immigrant integration or restrictions. This thesis offers original insights into current dynamics in immigration federalism through interviews with lawmakers and community activists in Arizona, a leading state when it comes to restricting the lives of undocumented immigrants. Advancing a new framework that connects the lived experience of officials and activists to partisanship, policy, key events, demographics, and racializing events, this thesis bridges isolated bodies of scholarship on immigration and seeks to demonstrate how every person (not just immigrant) are part of America’s current challenges to become a more inclusive nation of immigrants.

To investigate the impacts of an energy efficiency retrofit, indoor air quality and resident health were evaluated at a low‐income senior housing apartment complex in Phoenix, Arizona, before and after a green energy building renovation. Indoor and outdoor air quality sampling was carried out simultaneously with a questionnaire to characterize personal habits and general health of residents. Measured indoor formaldehyde levels before the building retrofit routinely exceeded reference exposure limits, but in the long‐term follow‐up sampling, indoor formaldehyde decreased for the entire study population by a statistically significant margin. Indoor PM levels were dominated by fine particles and showed a statistically significant decrease in the long‐term follow‐up sampling within certain resident subpopulations (i.e. residents who report smoking and residents who had lived longer at the apartment complex).
