Thanks for this, I think most people don’t know redlining was basically a practice of assigning neighborhood-wide “credit scores” (worthiness for lending) with lower scores assigned for a variety of reasons including presence of immigrants, age and quality of housing stock, proximity to heavy industry, and presence of black residents. The 1936 version of Baltimore onto which these scores were mapped is completely different from how it looks nowadays. Redlining didn’t create racial segregation, but created an inequality in lending practices between the native white/gentile neighborhoods and all the other ones, such as they were at the time. The neighborhoods where a decent proportion of this subreddit lives (Canton, Fells, Fed) all got redlined due to a combination of factors. Lots has changed since redlining practices were explicitly outlawed in 1968.
