Homo population hasn’t really increased since the 1970’s as far as I can see.
The really important demographic change is that the city is much more Asian.
I like to go to little italy. I started noticing 20 years ago, Mexicans in the kitchen, Italians waiting tables.
I think Chinatown has slowly expanded with increasing number of immigrants starting with the turnover of Hong Kong and continuing today. Little Italy will soon be a thing of the past with a few surviving restaurants and only memories of the old fishermen.
Going to SF in two weeks. Anything new and worthwhile to see?
