Downtown Pittsburgh, the Golden Triangle, is so tiny that comprises only 1 census tract. Giving half of it is taken by the park, the highways and there are still plenty of office buildings there, it's a quite decent density. I also worked a broader definition, including 4 census tracts adding the Bluff, Craford-Roberts and the Strip districts.
Pittsburgh MSA and Allegheny County growing for the first time since 1950-1960 while the city of Pittsburgh almost ended positive, which would be the first time since 1940-1950. Very promising for the area.
