Giving by Generation: Who Actually Writes the Checks
The biggest checks are still Boomer checks. The fastest growth is in the generations behind them.

Key takeaways
- Baby Boomers gave an average of $3,256 to charity in 2024, nearly four times Gen Z's $867 average, according to Giving USA's Giving by Generation report (released 2025).
- Millennials passed Gen X in average annual giving in 2021 and have widened the lead since: $1,616 against $1,371 in 2024.
- Every generation's average grew from 2021 to 2024, with Boomers up 27% and Gen Z up 16%, so the map is shifting by degrees, not flipping.
- The often-quoted claim that Boomers give 41% of all donated dollars is a 2018 Blackbaud measurement. No current verified share-of-dollars split by generation exists.
- 63% of Gen Z respondents told the Give.org Donor Trust Report (2026) they might give more if asked or want charities to approach them more often, which makes asking the cheapest younger-donor strategy available.
Baby Boomers still write the biggest checks. In 2024 the average Boomer donor gave $3,256 to charity, against $1,616 for Millennials, $1,371 for Gen X, and $867 for Gen Z, according to Giving USA's Giving by Generation report. The order below the top has already changed once: Millennials passed Gen X in 2021 and have widened the gap since. This is a map that moves, but it moves by degrees, and reading it well means holding two truths at once.
Which generation gives the most?
Boomers, by a wide margin. Giving USA's Giving by Generation special report, released in 2025 with 2024 data, puts the average Boomer donor's annual giving at nearly four times the average Gen Z donor's. These are averages per donor per year, not totals per generation, and the distinction matters for everything that follows.
| Generation | Average annual giving (2024) | Change since 2021 |
|---|---|---|
| Baby Boomers | $3,256 | +27% |
| Millennials | $1,616 | +22% |
| Gen X | $1,371 | +12% |
| Gen Z | $867 | +16% |
What the averages do not tell you is each generation's share of total dollars, because share depends on how many donors each generation has, not just how much each one gives. An average is a per-person number. Treating it as a share of the pie is the most common misreading of generational data, and it leads straight to the next question.
Who holds the largest share of the dollars?
The honest answer: the last verified public split is old. Blackbaud Institute's The Next Generation of American Giving, published in 2018, measured Boomers at 41% of all dollars donated, Gen X at 23%, and Millennials at 14%. Those numbers are eight years old. They described a real distribution in 2018, and they should be quoted with that year attached, never as the current state.
| Generation | Share of dollars (2018) |
|---|---|
| Baby Boomers | 41% |
| Gen X | 23% |
| Millennials | 14% |
Current data points the same general direction without giving a split. The Fundraising Effectiveness Project's Q4 2025 report found 2025's revenue growth came almost entirely from major and supersize donors while the number of donors fell 3.6%. That is concentration by gift size rather than by birth year, but combined with the average-gift ladder above, both patterns say the same thing: most of the dollars funding this year's budgets still come from older and larger donors.
What has actually changed?
Two things. First, the order in the middle: Millennials passed Gen X in average annual giving in 2021, and by 2024 the gap had grown to $1,616 against $1,371. Second, the direction everywhere: every generation's average rose from 2021 to 2024, and Gen Z's 16% growth outpaced Gen X's 12%. Gen Z writes the smallest checks of the four generations and is growing faster than the generation two ahead of it.
Appetite has moved too. The Give.org Donor Trust Report 2026 found 42.1% of Americans open to being approached by charities, near the highest level recorded since the survey began in 2017, and 28% said they might give more if asked. Among Gen Z the openness is starker.
What should you change for younger donors?
Add, do not swap. The moves below are additions to a program that keeps serving the donors who fund it today.
- 1.Make the phone path work. Mobile devices produced 52% of nonprofit website traffic in 2025, but donation pages converted at 8% on mobile against 11% on desktop, and the average mobile gift was $88 against $168 on desktop (M+R Benchmarks 2026). Those are device numbers, not generational ones, but a giving page that fails on a phone fails whichever generation is holding it.
- 2.Ask more often than feels polite. 63% of Gen Z respondents told Give.org (2026) they might give more if asked or want to be approached more often. Silence is not respect here. It is a missed invitation.
- 3.Invite monthly giving, then onboard hard. 71% of monthly donors are still giving twelve months after they start, and the first two months are the highest-churn window (M+R Benchmarks 2026), so the welcome matters as much as the upgrade ask itself.
- 4.Watch the youngest sustainers as their own cohort. Sargeant and Jay's sustainer research (2004) found donors recruited under 30 lapsed most often, usually on financial triggers, and advised weighting sustainer acquisition toward donors 30 and over. Track under-30 sustainer retention as its own number instead of judging the whole monthly program by it.
What should you not change?
Do not cut the stewardship your older donors already respond to in order to chase an average that is a quarter the size. The Boomer average of $3,256 funds this year's budget. Boomer donors are also the generation entering the bequest window, where the largest gift most donors ever make gets decided, and that conversation only happens inside a relationship that stayed warm.
The generational handoff is a slope, not a cliff. Growth rates say younger generations are coming up. Averages say they are not there yet. A plan built on either sentence alone gets the next decade wrong.
How do you map your own file?
Tag every donor with a birth year or an age band, then run average gift, retention, and channel mix per generation from your own records. The sector cannot hand you a current channel split by generation, but your file can, and your file's version is the one that describes your donors rather than everyone's. Donor personas and cohort analysis are the natural next steps once the generational column exists.
Start with one column: birth decade. Most of the map draws itself from there, and the version it draws is yours.
Frequently asked questions
- Which generation gives the most to charity?
- Baby Boomers, by average annual giving: $3,256 per donor in 2024, against $1,616 for Millennials, $1,371 for Gen X, and $867 for Gen Z (Giving USA, Giving by Generation, 2025). These are per-donor averages, not each generation's share of total dollars.
- Do Millennials give more than Gen X?
- On average per donor, yes. Millennials passed Gen X in average annual giving in 2021 and widened the lead to $1,616 against $1,371 by 2024 (Giving USA, Giving by Generation, 2025).
- What share of donations comes from each generation?
- No current verified split exists. The last verified public measurement is Blackbaud Institute's 2018 study: Boomers 41% of dollars, Gen X 23%, Millennials 14%. Quote it with the year attached, and read concentration on your own file for the current picture.
- How should organizations approach Gen Z donors?
- Ask them. 63% of Gen Z respondents told the Give.org Donor Trust Report (2026) they might give more if asked or want charities to approach them more often. Pair the ask with a giving page that works on a phone and, for new monthly donors, a strong first-two-months welcome.
- Should budget move from older donors to younger ones?
- No. Add younger-donor paths rather than swapping. Boomer donors still hold the largest averages by a wide margin and are entering the bequest window, so cutting their stewardship to fund youth outreach trades this year's revenue and future legacy gifts for a cohort that is still growing into its giving.
