This Quora response uses US Bureau of Labor Statistics to show there are 92,350 programmers in the whole SF Bay area, compared to 62,530 programmers in the entire NYC municipal area. So about 50% more in the Bay. https://www.quora.com/How-many-software-engineers-work-in-Si...
WNYC had a segment about this last week and claimed that there are 110k tech workers in the NYC area.
In fact, if there are only 110k tech workers, I doubt there are 92,350 actual programmers in NYC. They are counting all Product Managers, designers, beta testers, etc, as well as probably sales and administrative assistants in outfits like Google.
