What Charleston Moves does
Mission
Charleston Moves is a nonprofit organization that advocates for bicycle, pedestrian and public transit infrastructure and policies across Charleston County. We envision a connected community where safe transportation choice enhances access to essential resources like food, healthcare and employment, fostering equity and well-being for all. We envision strong, diverse neighborhoods where school children, folks in wheelchairs, and people with canes cross streets safely in their own time. We see streets lined with homes, bustling shops and restaurants. We see bridges and waterways where people on bicycles and on foot travel alongside buses and cars on their way to work, to the doctor, to the grocery store freely and safely.
As stated on its FY2025 Form 990.
Program
We believe in a connected Charleston. That's why we speak out to councils, committees, agencies, and even the State House, advocating for sound policies. Why we push to flourish, not stagnate. Why we work with urban planners, engineers and citizen groups. Study, audit and document the dangers and issues of our intersections, corridors and bridges and work to make them better, safer and more accessible. This is our determined, continuous commitment to remake systems and power enduring change.Because the streets belong to everyone. Pedestrians and school kids. People on bicycles and people on buses. Citizens in wheelchairs and with canes. (See Schedule O)All of us moving. Safely. Together. For the 2025 year, $.90 cents of every dollar spent went to our charitable programs.What We Are Doing:Bridges Front-and-Center Bridges should serve as connectors instead of barriers. For the new Ashley River Bicycle & Pedestrian Bridge, we have continued to watchdog the project, the construction of which is moving quickly with the western approach platform in place, and pile work continuing in the river. Collaborating with our coalition and Charleston County, we assisted with the County's fourth…

The program described on its FY2025 Form 990. Program spending in total: $183,334.
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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $295k to $468k (+59%).
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: 2020 14% · 2021 12%. Grants only. Government contracts and fees sit inside program revenue.
96% of Charleston Moves’s revenue is contributions — more reliant on donations than three-quarters of its peers (18% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 9 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 3 funders to 10 funders, grant income rose $83k → $102k.
5 of 24 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 30% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of Charleston Moves’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
Charleston Moves has a broad base — no single funder exceeds 24% 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
38% 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 Charleston Moves.
Largest funder’s share by year: 2017 60% · 2018 88% · 2019 71% · 2020 76% · 2021 46% · 2022 45% · 2023 38% — 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–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
42% of Charleston Moves's funders are still giving 3 years after their first grant; 38% 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
Charleston Moves draws 87% of its grant income from funders outside South Carolina, across 11 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $183k arriving through sponsors registered in 5 states 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–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Against its field
Charleston Moves runs a healthier operating margin than three-quarters of the 10,453 recreation & sports nonprofits its size.
