The highest concentration of the Gujarati American population by a significant margin, with over 100,000 Gujarati individuals, is in the New York City Metropolitan Area, notably in the growing Gujarati diasporic center of India Square, or Little Gujarat, in Jersey City, New Jersey, and Edison in Middlesex County in Central New Jersey. Significant immigration from India to the United States started after the landmark Immigration and Nationality Act of 1965,[12][13] Early immigrants after 1965 were highly educated professionals. Since US immigration laws allow sponsoring immigration of parents, children and particularly siblings on the basis of family reunion, the numbers rapidly swelled in a phenomenon known as "chain migration". Faith plays a big role in the rapidly growing Gujarati community in North Texas, which has three large Hindu temples. Census numbers showed that from 2000 to 2010, the population more than doubled, going from 49,181 to 106,964 for Collin, Dallas, Denton, Rockwall and Tarrant counties. Richardson has a long-established Gujarati population, and it was there that a group of businessmen founded the India Association of North Texas (1962). Changes in recent years have been more drastic.
