It's interesting to hear the population estimates on China Town and Calle Olvera: 3000 for both.
They were tiny, remnant populations since LA was a little under 2 million in 1946 (about 0.2% in both cases).
It reminds us of the enormity of the invasion since then, really getting underway in about 1970. Los Angeles is now predominantly Mexican, with well over 2 million in LA proper.
My mother spoke fluent Spanish and told me she never used it when she lived in West LA in the late '40s. There was just no reason to - except if you took a stroll through East LA, i.e., Olvera Street.
Downtown LA, where my great uncles worked, was like the western version of New York. An American big city, one of the defining places.
It was interesting to me because of what the various cultures actually added to the area and ambience back then; which quality I agree is very different from what they bring today.
But I believe a lot of the reason for that is an all-around decline in the various cultures themselves. Our own culture hasn’t been innocent of a steep decline.
