I spent my senior year of high school studying gentrification and demographic patterns in the District for my senior thesis and used these three sources extensively, they're superb books that are great reads for anyone even remotely interested in the District. They're pretty pricey to buy, but DCPL has each book, and the last one is available for Kindle.
City of Magnificent Intentions is an amazing book. It's the DCPS textbook for D.C. History (mandatory to graduate high school) and is filled with great facts, photos and drawings. Although it's formatted like a textbook, it is still a fantastic history of the city. It does a great job addressing planning and general demographics. It's probably one of the best books on D.C.
Dream City: Race, Power, and the Decline of Washington, D.C. is a fascinating read on the politics and racial history of the District, and it's co-authored by Harry Jaffe and Tom Sherwood! It has a great section on the riots, how they affected the District, and the rise (and I believe also the fall) of Marion Barry.
The Great Society Subway is an incredibly detailed history of Metro, but might also interest you based on the way it details the impact it made on various sections of the city and suburbs (For instance, it goes in depth about how the green line was the last line built and how that impacted the neighborhoods it passed through, often the poorest in the city).
