For example, Graph 5a is "Immigrant Groups Founding Engineering and Technology Companies in California." India is out in front at 20%, followed by Taiwan (13%), and China (10%). This time, Mexico makes the chart, but with only 1%. That's not a lot of return for having 10,000,000 Mexicans in California.
Similarly, Chart 10 shows patent applications by non-citizen immigrants over the last 20 years. Mexicans, who are by far the largest number of non-citizens in America, don't even make the top 20: Chinese & Taiwanese are first, followed by India, Canada, UK, Germany, France and Russia. Heck, Turkey makes the top 20, and there are hardly any Turks in America. But not Mexico (or any other Latin American country).
