What the HeyAlbert database shows in Lake County, Illinois
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 217 such people in Lake County, Illinois [8]. 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 |
|---|---|
| $1M–5M | 191 |
| $5M–15M | <25 |
| $25M+ (probable) | <25 |
| $25M+ (likely) | <25 |
| Total, $1M+ | 217 |
Source: HeyAlbert database [8]. Bands are estimates from public evidence; “likely” and “probable” describe our confidence in the $25M+ tier. Cells under 25 are suppressed.
| City | $1M+ | of which $5M+ | of which $25M+ |
|---|---|---|---|
| Lake Forest | 51 | <25 | <25 |
Source: HeyAlbert database [8]. 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. Cities in our database are matched by name to the Census places and townships in the county; a few that straddle a county line are counted whole, and large cities that extend well beyond the county are left out.
Lake Forest has 51 people in our set, fewer than 25 of them at $5M+ [8]. Buffalo Grove and Vernon Hills are not among the cities with 25 or more people in our set [8]. Across the county, 26 people are at $5M+, and fewer than 25 are in our $25M+ bands [8].
Why our Lake County, Illinois count looks the way it does
Each estimate in our database rests on a primary piece of public evidence. The mix differs from place to place, depending on which records we have been able to process, and it shapes the counts above more than any real difference in wealth does [8].
| Primary evidence for the estimate | People | Share |
|---|---|---|
| Home value (public assessor or listing records) | 189 | 87% |
| Other public signals (executive roles, company filings, gifts, pay) | 28 | 13% |
Source: HeyAlbert database [8], people at $1M+. Categories under 25 not shown.
Home values support 189 of our 217 estimates and other public signals 28 [8].
What it means if you work with these families
For advisors and nonprofits, Lake County grew about 36% in the Census, but our records there are still thin outside Lake Forest [1][2][8].
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 October 2026 [8]. 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.
