WASHINGTON: For the longest time, Red states and Blue states in America have typically referred to Republican and Democratic leaning states in political and electoral terms. But in the world of immigration and demographics, it turns out they illustrate dominant Hispanic (mostly Mexican) and Asian (mostly Indian) populations.Amid reports that indicate India and China are now starting to send more legal immigrants to the United States than Mexico, new data from the US department of homeland security shows that Asian Indians form the biggest group of naturalized Americans in nine states, mostly in eastern US.Mexican-Americans still dominate the central and western half of the US, but the fact Indians have such a high concentration in so many states comes as much as a surprise as Chinese not being the top immigrant population even in a single state.Overall, Mexicans remain the single largest group of foreigners who were naturalized as citizens between 2003 and 2013, the decade for which DHS has released annualized data. But by state, Mexicans are the biggest group in only 24. Among the remaining 26 states plus the District of Columbia, 10 other nationalities claim the top spot, as this map shows.In nine states, Indians make up the biggest group of naturalized citizens. Those from the Dominican Republic, who nationwide topped those from China for the first time in at least a decade, are the biggest group in five states, the DHS data shows.Each year, roughly between 800,000 to a million immigrants become naturalized US citizens. By country, the biggest groups after Mexico are India, Philippines, Dominican Republic and China. In recent years, more and more Indians are taking up US citizenship. DHS data from 2003-2013 shows Indians taking up US citizenship growing from about 30,000 annually to more than 60,000 annually towards the end of the decade, accounting for some 500,000 Indians who became American citizens in those 10 years.\Although they are outnumbered in California by Mexicans taking up US citizenship, the Golden State still remains their #1 destination. But in nine other states, including New Jersey, New York, Ohio, and Maryland, Indian-Americans top Mexicans-Americans numerically in terms of taking up citizenship.The DHS data also shows that more than 50% of the emigrating Indians are in prime earning age of 25-44, suggesting that the US is benefiting from giving citizenship to productive immigrants. Retirees and homemakers formed less than 10% of Indians who got citizenship in 2013. Some 35% of Indian immigrants who took US citizenship worked in management, professional, service, production and sales occupations.
