The Free Application for Federal Student Aid (FAFSA) is an important application that prospective college students must complete to qualify for state and federal aid. This report describes how school district FAFSA completion rates are related to district-level poverty rates across and within states. Given that students from low-income backgrounds may be particularly dependent on financial aid to make postsecondary education affordable, it might be reasonable to hypothesize that districts that serve higher-poverty student populations also have higher FAFSA filing rates than their wealthier counterparts. Unfortunately, the opposite is found -- that, in most states, districts with higher rates of poverty have lower FAFSA completion rates. This trend is observed both across states and across districts within states.
