The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2017 49% · 2018 47% · 2019 41% · 2020 55% · 2021 66% · 2022 82% · 2023 69% · 2024 59% · 2025 21%. Grants only. Government contracts and fees sit inside program revenue.
38% of Population Reference Bureau Inc’s revenue is contributions — about as donation-reliant as the typical peer (82% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 9 reported years ran a deficit.

From the IRS filings of Population Reference Bureau Inc’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
Population Reference Bureau Inc has a broad base — no single funder exceeds 27% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left

“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
53% of Population Reference Bureau Inc's funders are still giving 3 years after their first grant; 48% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
Population Reference Bureau Inc draws 97% of its grant income from funders outside Washington, D.C., across 11 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $97k arriving through sponsors registered in 4 statesis excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
