Philanthropy
Foundations are matched to a person by name, not by trustee records — so a same-surname family foundation can land here in error. Every entity below links to its full IRS filing; if one doesn’t belong, tell us at hello@skylarkcreations.com and we’ll pull it.
Political Contributions
These figures cover the 100 most recent federal contributions on file, not the full record. The total, party split, top recipients and dates below are all computed over that sample, so each is a floor rather than a complete figure.

Matched by name only. These are the donations the FEC lists under this person’s name — so a different person with the same name can show up here too.
Score Breakdown
The PBS is a weighted average of 2 components. The formula is open and versioned — the weight percentages below show how much each component contributes to the final score.
Evidenced charitable giving — built on what they actually give each year, not parked assets. Dominated by generosity (annual giving relative to net worth — the share of your fortune you give), plus the absolute scale of that giving, plus a small nudge for signing the Giving Pledge (a commitment, not a realized action).
