I would say that life in the cities became more liveable in the late 1800's and early 1900's because for one thing the public mass transportation improved such as with the development of street cars and buses so people could move around more easily. Also, I believe street lighting improved then as well so that streets were well illuminated. Also, housing probably started to include multiple dwellings so many people could live in the same complex but having their own privacy and own facilities.
