The population of Indian-origin people in grew by 38 per cent in seven years between 2010 and 2017, a South Asian advocacy group has said in its latest demographic report.

There are at least 630,000 who are undocumented, a 72 per cent increase since 2010, the South Asian Americans Leading Together (SAALT) said in its snapshot.

The increase in illegal Indian-Americans can be attributed to Indian immigrants overstaying visas, it said.

Nearly 250,000 overstayed their visa in 2016 therefore becoming undocumented, it said.

In general, the population of American residents tracing their roots to grew by 40 per cent. In real terms, it increased from 3.5 million in 2010 to 5.4 million in 2017, SAALT said.

The Nepali community grew by 206.6 per cent since 2010, followed by Indian (38 per cent), Bhutanese (38 per cent), Pakistani (33 per cent), Bangladeshi (26 per cent) and Sri Lankan populations (15 per cent).

There are currently at least 4,300 active South Asian Deferred Action for Childhood Arrivals (DACA) recipients. As of August 2018, there are approximately 2,550 active Indian DACA recipients. Only 13 per cent of the overall 20,000 DACA eligible have applied and received DACA.

SAALT said that as far as DACA recipients from other countries are concerned, there are 1,300 from Pakistan, 470 from Bangladesh, 120 from and 60 from

The immigrant population density of the country shows that undocumented Bangladeshi immigrants live in (19,000); Michigan (4,000); (3,000); and (2,000).

The demographic snapshot is based primarily on Census 2010 and the 2017 American Community Survey.

According to the report, income inequality has been reported to be the greatest among Asian Americans.

Nearly one percent of the approximately five million South Asians in the US live in poverty.

SAALT said there has been a rise in the number of South Asians seeking asylum in the US over the last 10 years.

The US Immigration and Customs Enforcement (ICE) has detained 3,013 South Asians since 2017. US Customs and Border Patrol arrested 17,119 South Asians between October 2014 and April 2018 through border and interior enforcement, it said.

According to SAALT, since 1997, more than 1.7 million dependent spouses of H-1B visa holders have received H-4 visas.

In 2017, 136,000 individuals received H-4 status. Nearly 86 per cent of H-4 visa holders are from South Asian countries.

In 2015, DHS granted work authorisation to certain H-4 visa holders. As of December 2017, approximately 127,000 visa holders were approved for H-4 EAD, the report said.

Nearly 472,000 or 10 per cent of the approximately five million South Asians in the US live in poverty, the report said.

Among South Asian Americans, Pakistanis (15.8 per cent), Nepalis (23.9 per cent), Bangladeshis (24.2 per cent), and Bhutanese (33.3 per cent) had the highest poverty rates, it said.

Bangladeshi and Nepali communities have the lowest median household incomes out of all Asian American groups, earning USD 49,800 and USD 43,500 respectively, it said.

Nearly 61 per cent of non-citizen Bangladeshi American families receive public benefits for at least one of the four federal programmes including TANF, SSI, SNAP and Medicaid/CHIP, 48 per cent of non-citizen Pakistani families and 11 per cent of non-citizen Indian families also receive public benefits, the report said.

In the lead up to the 2020 elections, South Asians are becoming an increasingly powerful segment of the American electorate, SAALT said.

According to the Current Population Survey (CPS), 49.9 per cent of voting-age, Asian American citizens cast a ballot in 2016. The number of Asian American voters in the last decade has nearly doubled from about two million voters in 2001 to 5 million voters in 2016.

Of these, Indians account for more than 1.5 million, followed by Pakistanis (222,252) and Bangladeshi (69,825), SAALT added.
