What is San Mateo’s federal contribution total on LobbyVault?

Itemized FEC.gov receipts listing contributor city SAN MATEO, CA total $52,488,589 across 105,268 contributions. That pair is a city-string roll-up of federal Schedule A rows, not a unique-donor count and not a census of San Mateo residents. Unitemized gifts sit outside both figures.

How should I read San Mateo’s 105,268 contributions?

LobbyVault counts 105,268 itemized lines for SAN MATEO, CA. That is a line count, not a headcount of unique people. Repeat gifts and memo entries can add rows without adding donors. This packet publishes no unique-donor figure. The matching dollar total is $52,488,589.

Does San Mateo’s total include the rest of San Mateo County?

No. This hub is the city string SAN MATEO, CA. Foster City, Burlingame, and Hillsborough are separate city strings when they appear that way on the receipt. $52,488,589 is the SAN MATEO, CA match. The 105,268 lines follow the same rule. County labels are not an FEC dimension on this hub.

Where do the San Mateo facts come from?

Both facts come from FEC.gov itemized contribution aggregates indexed on LobbyVault: $52,488,589 and 105,268 lines. Original reports remain on FEC.gov. California non-federal filings are outside the pair. If a later extract disagrees, the Commission’s filing controls. The mean of about $499 is arithmetic from those two packet numbers.

What $52,488,589 on the San Mateo city field covers

$52,488,589 divided by 105,268 is about $499 per itemized line. That mean is arithmetic from the two packet facts. FEC.gov does not publish a median, a unique-donor count, or a party split on this city aggregate. LobbyVault reports $52,488,589 and 105,268.

San Mateo County’s namesake city sits on this string as a mid-Peninsula filing city, not as a score of countywide races. The city total can include a PAC or joint-fundraising committee address when that is the city filers typed. LobbyVault does not recode those rows out of the city string.

A San Mateo total of $52,488,589 does not absorb Foster City, Burlingame, or Hillsborough. Those names are other city strings when filers typed them. State CA stays on the citation so SAN MATEO, CA is not merged with San Mateo County as a whole. The 105,268 lines and the mean near $499 describe this key only.

San Mateo is a contributor city, not a county roll-up

The city is the contributor-city value on FEC itemizations. Filers type it. LobbyVault does not geocode San Mateo against a municipal boundary file. A work address, a mail drop, or a household in a neighboring place that still typed SAN MATEO can sit inside $52,488,589.

Amended reports can raise or lower both $52,488,589 and 105,268. If the live San Mateo hub reprints different figures, the newer FEC extract wins.

City versus county on the Peninsula tape

Searchers often treat “San Mateo” as the county. This hub is the city string SAN MATEO, CA. Redwood City, South San Francisco, and Daly City keep their own keys when filers typed those names.

Atherton and Menlo Park are other Peninsula strings with their own aggregates. Adding them to San Mateo would be a recode. This packet publishes SAN MATEO, CA only: $52,488,589 and 105,268 lines.

What $52,488,589 from San Mateo omits

Unitemized federal contributions do not appear in $52,488,589. Many small gifts never become Schedule A city rows. Citing $52,488,589 as “all federal money from San Mateo” overstates the series.

California state campaigns file under state law. Those receipts are outside $52,488,589 and outside 105,268. Independent expenditures that never appear as contribution itemizations are outside both facts.

ZIP codes under the San Mateo city string

The ZIP directory cuts the same FEC itemized series by five-digit contributor ZIP. A San Mateo city total of $52,488,589 is not automatically the sum of ZIPs that the postal service assigns to San Mateo. Filers can type this city with a ZIP the postal service maps to Foster City or Belmont, and the reverse.

Do not treat a mean near $499 as proof that San Mateo ZIPs are “mid-dollar donor ZIPs.” This packet has no ZIP list and no income field. City and ZIP answer different questions. If the live hub reprints a different $52,488,589 or 105,268, the newer FEC extract wins and this snapshot is stale. Open original reports on FEC.gov when a named San Mateo receipt matters.

How researchers should use the San Mateo hub

Start on the live San Mateo city page, then open ZIP pages if a postal cut is the real question. $52,488,589 is the city-string dollar total in this snapshot. 105,268 is the matching line count. Those two numbers move together when FEC.gov amends a receipt. They do not move because a researcher prefers Foster City or Burlingame as the “real” mid-Peninsula. Filers typed SAN MATEO. LobbyVault indexed SAN MATEO. San Mateo County as a whole, the Caltrain corridor, and “the Peninsula” are useful for maps and news copy. They are not FEC dimensions on this hub.

A mean near $499 is only $52,488,589 divided by 105,268. It is not a typical San Mateo household gift, not a typical biotech-employee gift, and not a typical airport-corridor gift. Occupation is a different FEC field. Recipient is a different FEC field. Party is a different FEC field. None of those fields are in this packet. Do not infer them from the mean. Do not infer turnout. Do not infer that San Mateo is more or less “politically active” than Redwood City because the line counts differ. Redwood City is a different city string with its own hub.

Cite the pair in one sentence: contributor city SAN MATEO, CA, $52,488,589, 105,268 itemized federal contributions, source FEC.gov via LobbyVault. If a later extract on the live hub prints a different pair, discard this snapshot. Original PDFs and electronic filings remain on FEC.gov for any named San Mateo receipt that needs a line-by-line check. California non-federal filings never enter either fact. Unitemized federal gifts never enter either fact. Independent expenditures that are not contribution itemizations never enter either fact. That is the full scope of this city page.
