How Mamaroneck compares with nearby places
The Census Bureau's American Community Survey counts 248 people who report Asian Indian ancestry, alone or with another group, in Mamaroneck [1], against 75 in 2015–2019 [2]. The table compares it with the places in Westchester County that have the largest Asian Indian communities. Figures are for whole places, and some places extend into neighboring counties [1][2][4].
| Place | 2020–2024 | 2015–2019 | Change | Share of place |
|---|---|---|---|---|
| Yonkers | 4,258 | 6,295 | -32% | 2.0% |
| New Rochelle | 1,623 | 1,687 | -4% | 2.0% |
| White Plains | 1,589 | 1,750 | -9% | 2.6% |
| Scarsdale | 1,170 | 549 | 113% | 6.5% |
| Greenville CDP (Westchester County) | 1,102 | 774 | 42% | 11.9% |
| Mount Vernon | 963 | 627 | 54% | 1.3% |
| Ardsley | 540 | 237 | 128% | 10.8% |

Asian Indian alone or in any combination. Sources: ACS 5-year estimates [1][2][4]; totals from Table B01003. Change and share are our calculations. Estimates carry margins of error.
Mamaroneck's growth matches a wider Westchester pattern in this table. Scarsdale more than doubled to about 1,200, and Ardsley more than doubled to about 540 [1][2][4]. Yonkers, the largest community at about 4,300, fell by about a third [1][2][4].
The most concentrated communities
Raw counts favor big cities. Ranking places of 20,000+ residents by the share who report Asian Indian ancestry gives a different map [1][2][3][4][5]:
| Place | Asian Indian residents | Total population | Share |
|---|---|---|---|
| White Plains | 1,589 | 60,666 | 2.6% |
| Yonkers | 4,258 | 209,978 | 2.0% |
| New Rochelle | 1,623 | 82,769 | 2.0% |
Places with 20,000+ residents and at least 1,000 Asian Indian residents. CDP = census-designated place. Sources: ACS 2020–2024 5-year, Tables B02018 and B01003 [1][2][3][4][5]; shares are our calculation.
What the HeyAlbert database shows in Mamaroneck, New York
HeyAlbert builds profiles of Indian-American individuals with an estimated net worth of $1M or more from public records, and every estimate is tied to a cited source. Our database currently places 89 such people in Mamaroneck, New York [6]. That is a count of people we have found and estimated, not a census of wealthy households: our coverage is partial and uneven.
| Estimated net-worth band | People in our database |
|---|---|
| $5M+ | <25 |
| $1M–5M | not shown |
| Total, $1M+ | 89 |
Source: HeyAlbert database [6]. Bands are estimates from public evidence; $5M+ combines our $5–15M and $25M+ tiers. Cells under 25 are suppressed. When one tier has fewer than 25 people, the other tier is not shown either, because it could be subtracted from the total.
| City | $1M+ | of which $5M+ |
|---|---|---|
| Mamaroneck | 82 | <25 |
Source: HeyAlbert database [6]. Cities with 25+ people at $1M+; cells under 25 shown as <25. The city is where our sources place the person; for some records it is a workplace rather than a home. Our records are matched on the city name Mamaroneck; the Census figures are for the whole place.
Our database places 89 people in Mamaroneck at an estimated $1M+ [6]. Fewer than 25 of them are in our $5M+ bands, so this post shows the $1M+ total and does not split it by tier [6]. We match records spelled "Mamaroneck" and "Mamaroneck, Village"; the mailing name can cover more than the village itself [6].
Why our Mamaroneck, New York count looks the way it does
Each estimate in our database rests on a primary piece of public evidence [6]. In Mamaroneck, New York, most rest on one type: home value (public assessor or listing records). Because some evidence types here cover fewer than 25 people, and subtracting them from the total could reveal a suppressed tier, we do not show the evidence counts for this place.
Public home-value records support most of these estimates [6]. This is a homeowner set.
What it means if you work with these families
For advisors, Mamaroneck is a small but newly visible community in the Census data, with a $1M+ group in our set built mostly on home values [1][2][6]. Our Westchester, Scarsdale and Rye posts cover the area.
Methodology
Census figures are American Community Survey 5-year estimates for 2020–2024 and 2015–2019, Table B02018, using “Asian Indian, alone or in any combination” [1][2]. Total population comes from Table B01003 [3]. The Census Bureau changed how it codes detailed race responses in 2020, so part of the change between the two periods may reflect coding rather than migration. All estimates carry margins of error. Shares and growth rates are our calculations.
HeyAlbert counts are aggregates from our database as of November 8, 2026 [6]. They include people we identified as likely of Indian origin with an estimated net worth of $1M or more, based on public records such as property assessments, professional licenses, patents, SEC filings and donor rolls. Coverage is partial and depends on which public records exist and which we have processed. These counts are not population totals. Any cell under 25 is suppressed, and we publish aggregates only, never individual records.
