The organization over time
Each line starts at 100 in 2020, so what you read is the shape rather than the size: 150 means half as much again as 2020, 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.
99% of The Period Purse’s revenue is contributions — more reliant on donations than three-quarters of its peers (35% for the typical peer).

the vertical line marks half of all grant income — 2 funders to its left
100% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund The Period Purse.
Largest funder’s share by year: 2019 72% · 2020 78% · 2021 93% · 2022 53% · 2023 39% — diversifying over time.
“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 is still being filed and is shown unshaded; it does not move any figure on this page.
How long its funders stay
43% of The Period Purse's funders are still giving 3 years after their first grant; 67% 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
79% of The Period Purse's grant income comes from Ontario funders.
In-province vs out-of-province, by year
Funder regions come from each funder’s own filing. C$11k arriving through sponsors registered in 1 region is 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 is still being filed and is shown unshaded; it does not move any figure on this page.

These figures are read directly from the CRA's published T3010 data: this organization’s own return for FY2024 (financials across 2020–2024), and the filings of 24 funders that report grants to it. “On record” means captured in the filings we have parsed — a funder that does not e-file, or whose grant detail is not itemized, will not appear. Filings run roughly 12–24 months behind. Trends on this page end at FY2023, the last fiscal year that has finished arriving; later years are shown and marked, and move no figure.
