The United States is still the premier destination for high-growth businesses, but several cities in other parts of the world are climbing the rankings.

The Startup Genome recently released new start-up ecosystem rankings based on data collected from 50,000 young companies around the world. Researchers took into consideration each city’s total start-up output, availability of funding, wealth of talent, and other components considered vital to launching new businesses.

Silicon Valley, long regarded as the greatest start-up launching pad, topped the rankings in every category. The United States placed six cities and Canada placed two in the top 10. Tel Aviv, Israel came in just behind the Valley in the No. 2 slot, with London, England the only other non-North American city listed among the top 10.

For a look at the top 15, check out the gallery above.
