The numbers, with their vintages

2020 count · 2024 estimate · ACS 2020–2024 survey

The count: 1,623 people at the 2020 census. The estimates program: 1,632 at July 1, 2024 — the same published table gives 1,631 (2023), 1,625 (2022), 1,624 (2021), 1,626 (July 1, 2020), on an April 1, 2020 estimates base of 1,628. The estimates base (1,628) is NOT the decennial count (1,623) — the two instruments differ by construction and print side by side, never merged (conflict C70; this also explains the "2020 = 1,628" line flagged in conflict C4 — it is the estimates base, not a rival count). No July 1, 2025 figure was reached (gap G-TD-2). The survey estimate (ACS 2020–2024): total population 1,775 — a survey estimate, printed as one, never as a count. Median age 33.5 years (the 2020 census median was 34.3 — different instrument, both printed). Households 711. Median household income $75,047; median family income $77,336; per-capita income $40,387. Poverty: 147 persons, 8.3% of persons for whom poverty status is determined; under-18 poverty 10.9%; 65+ poverty 5.6%. Housing: 764 units, 711 occupied (93.1%); owner-occupied 78.1%; median home value $162,100; median gross rent $960; 89.7% single-family units; 37.7% of units built 1939 or earlier, only 4.7% built 2010 or later. Residents' work (industry of employed residents — NOT in-town jobs): manufacturing 202 (26.9%); transportation, warehousing and utilities 141 (18.8%); educational services and health care 122 (16.2%); mean travel time 26.3 minutes; 82.8% drive alone, 8.9% work at home. The 2015 Comprehensive Plan's era figure for manufacturing was 27.6% — two vintages, both dated, no conflict. One county-table figure is flagged, not adopted: STATS Indiana's county profile lists North Liberty at 1,624 in a "2025" largest-cities table, while its own estimates table gives 1,624 as the July 1, 2021 estimate (conflict C71). And the anomalies stand: 2000→2010 +35.2%; 2010→2020 −14.4%, the largest decline in the series, while the Gazetteer area rose 0.98→1.04 sq mi — unexplained in the record, and no explanation is offered. Two carrier variances print with the numbers rather than being silently dropped: older survey vintages print lower median household incomes ($71,272; $58,125) against this release's $75,047 — successive vintages of the same survey with wide small-town margins (conflict C72) — and a population aggregator prints "2026 population 1,624" against the published table's 1,632 for 2024; the aggregator is not adopted and the published table governs (conflict C73).
