Redlines and Greenspace: The Relationship between Historical Redlining and 2010 Greenspace across the United States.

ABSTRACT:

Introduction

Redlining, a racist mortgage appraisal practice of the 1930s, established and exacerbated racial residential segregation boundaries in the United States. Investment risk grades assigned >80y ago through security maps from the Home Owners' Loan Corporation (HOLC) are associated with current sociodemographics and adverse health outcomes. We assessed whether historical HOLC investment grades are associated with 2010 greenspace, a health-promoting neighborhood resource.

Objectives

We compared 2010 normalized difference vegetation index (NDVI) across previous HOLC neighborhood grades using propensity score restriction and matching.

Methods

Security map shapefiles were downloaded from the Mapping Inequality Project. Neighborhood investment risk grades included
