From the annual returns the group files with the IRS (Form 990, or the shorter Form 990-EZ for smaller groups), 2 filed years. Net assets are what it owns minus what it owes; management and general is office, admin and insurance cost. A dash means not reported (the short form does not ask for employees or volunteers). Each figure links to that year's return. A year is left out when no return is in the IRS e-file data; that does not mean the group was inactive.

Revenue trend: Growing. Revenue went from $121,598 (year ending Dec 2022) to $134,101 (Dec 2023), about +10% a year.
Growth label: we compare total revenue on the oldest and the newest return shown above. Growing means revenue rose by more than 10% a year on average, Shrinking means it fell by more than 10% a year, and Steady means a change between -10% and +10% a year. The rate is the compounded yearly average between the two returns, so it hides ups and downs in between (see the table). We only label groups with returns at least a year apart and at least $5,000 of revenue on the oldest one. This is our own calculation, not an IRS rating or a judgment of quality.
