The fastest-growing Indian-American counties in the US

The Indian-American population is growing quickly, but not evenly. Nationally, the Census Bureau's estimate of people reporting Asian Indian ancestry, alone or in combination, rose from about 4.32 million in the 2015–2019 survey to about 5.06 million in 2020–2024, an increase of roughly 17% [5][6] (our calculation). At the county level, some places grew several times faster than that, while some of the oldest communities shrank.

This post ranks US counties by that growth, using the same Census table for both periods, and explains why the pattern matters for anyone who serves Indian-American families.

The fastest-growing large communities

Among the 53 counties that had at least 20,000 residents of Asian Indian descent in 2015–2019, Forsyth County, Georgia, grew fastest, at about 89%, followed by San Joaquin County, California (about 75%), and Collin County, Texas (about 66%) [1][2]. Denton County, Texas, and Wake County, North Carolina, complete the top five [1][2].

County	2015–2019	2020–2024	Change	Share of county, 2020–2024
Forsyth County, Georgia	20,189	38,084	+89%	14.2%
San Joaquin County, California	23,114	40,358	+75%	5.1%
Collin County, Texas	71,840	119,401	+66%	10.3%
Denton County, Texas	33,416	51,715	+55%	5.3%
Wake County, North Carolina	39,988	57,693	+44%	4.9%
Lake County, Illinois	20,383	27,752	+36%	3.9%
King County, Washington	89,918	121,551	+35%	5.3%
Contra Costa County, California	37,394	48,735	+30%	4.2%
Somerset County, New Jersey	31,230	40,409	+29%	11.6%
Tarrant County, Texas	23,814	30,378	+28%	1.4%
San Francisco County, California	23,242	29,237	+26%	3.5%
Dallas County, Texas	64,380	80,683	+25%	3.1%
Hillsborough County, Florida	26,065	32,584	+25%	2.1%
Broward County, Florida	28,978	36,140	+25%	1.8%
Loudoun County, Virginia	39,342	48,986	+25%	11.3%

Counties with at least 20,000 Asian Indian residents (alone or in any combination) in 2015–2019. Sources: ACS 5-year Table B02018 [1][2]; county population from Table B01003 [3]. Change and share are our calculations.

The list has a clear geography. Four of the top fifteen are in the Dallas–Fort Worth area (Collin, Denton, Tarrant and Dallas counties) [1][2]. The rest are mostly suburban counties on the edge of established tech and finance hubs: San Joaquin and Contra Costa outside the Bay Area, Lake County outside Chicago, Somerset in central New Jersey, Loudoun outside Washington DC, and Forsyth north of Atlanta [1][2].

The largest gains in raw numbers

Percentages favor smaller bases. Ranked by the number of people added, Collin County leads by a wide margin, adding about 47,600 residents of Asian Indian descent between the two surveys, followed by King County, Washington (about 31,600) and Alameda County, California (about 26,700) [1][2].

County	2015–2019	2020–2024	People added
Collin County, Texas	71,840	119,401	+47,561
King County, Washington	89,918	121,551	+31,633
Alameda County, California	134,144	160,849	+26,705
Santa Clara County, California	185,680	208,719	+23,039
Denton County, Texas	33,416	51,715	+18,299
Forsyth County, Georgia	20,189	38,084	+17,895
Wake County, North Carolina	39,988	57,693	+17,705
Williamson County, Texas	18,499	36,095	+17,596
Middlesex County, New Jersey	133,139	150,707	+17,568
San Joaquin County, California	23,114	40,358	+17,244
Dallas County, Texas	64,380	80,683	+16,303
Snohomish County, Washington	17,937	30,502	+12,565

Sources: ACS 5-year Table B02018 [1][2]; our calculation. Connecticut is excluded from this ranking because it replaced its counties with planning regions in Census data after 2020, so the two periods do not match.

Fast-rising mid-size communities

Below the 20,000 threshold, a second group is growing even faster. Williamson County, Texas, north of Austin, nearly doubled, and Snohomish County, Washington, grew about 70% [1][2]. Hamilton County, Indiana (the Carmel and Fishers area), and Delaware and Warren counties in Ohio show that the growth is not confined to the coasts [1][2].

County	2015–2019	2020–2024	Change
Williamson County, Texas	18,499	36,095	+95%
Hamilton County, Indiana	7,281	12,729	+75%
Snohomish County, Washington	17,937	30,502	+70%
Albany County, New York	5,799	9,641	+66%
Benton County, Arkansas	5,569	8,259	+48%
Douglas County, Colorado	7,092	10,498	+48%
Marion County, Indiana	7,444	11,016	+48%
Delaware County, Ohio	8,208	12,061	+47%
Warren County, Ohio	7,286	10,599	+45%
Cumberland County, Pennsylvania	5,226	7,519	+44%

Counties with 5,000–19,999 Asian Indian residents in 2015–2019. Sources: ACS 5-year Table B02018 [1][2]; our calculation.

Where the community shrank

Seven of the 53 large counties had fewer residents of Asian Indian descent in 2020–2024 than in 2015–2019 [1][2]. Queens, historically one of the country's largest Indian-American communities, fell about 11%, and Brooklyn, Fairfax, Los Angeles and Bergen counties also declined [1][2].

County	2015–2019	2020–2024	Change
Queens County, New York	149,507	132,937	-11%
Kings County, New York	37,375	35,091	-6%
Fairfax County, Virginia	59,875	57,099	-5%
Hennepin County, Minnesota	26,957	25,709	-5%
Los Angeles County, California	116,854	112,845	-3%
Bergen County, New Jersey	36,301	35,304	-3%
Franklin County, Ohio	25,599	25,354	-1%

Large counties (20,000+ in 2015–2019) with a lower 2020–2024 estimate. Sources: ACS 5-year Table B02018 [1][2]; our calculation. Several of these changes are within the surveys’ margins of error.

What it means

The movement is from dense, expensive inner suburbs to newer, larger-home suburbs farther out, and from the coasts toward Texas, Georgia and North Carolina. For financial advisors, real-estate professionals and nonprofits, that means the families you met in Queens or Fairfax ten years ago may now be in Nassau, Loudoun's newer subdivisions or Collin County. In our own database, many of these fast-growth suburbs show large numbers of people in the $1M–5M band, often on home-equity evidence, which you can see in our Texas, Georgia, North Carolina and Washington posts [4].

Methodology

All counts are ACS 5-year estimates from Table B02018, “Asian Indian, alone or in any combination”: variable B02018_002 in the 2015–2019 release and B02018_021 in the 2020–2024 release, which carry the same definition after the table was renumbered [1][2]. County population comes from Table B01003 [3]. The Census Bureau changed how it codes detailed race responses in 2020, so some of the change may reflect coding rather than migration, and every estimate has a margin of error. Growth rates and rankings are our calculations. Counties are matched across periods by their Census geographic identifiers.
