Ghost Layers of Memphis

This is a visual aid, not an official city publication. It stacks a 1930s HOLC map, a present-day continuation estimate, and today's burden score so you can see where older decisions still appear to shape Memphis.

How to read this map

Fast read: warm colors usually mean old exposure and present-day strain still line up. Cool colors usually mean protection held more strongly.

View Mode

Composite Read gives each tract one plain-language pattern name based on all three layers.
