ZIP 48103: $17.8 million across 106,067 FEC lines

106,067 lines on a $17.8 million ZIP

Divide $17,838,412 by 106,067 and the typical itemized line is about $168. That is the extreme high-volume end of this set: more receipts than any other remaining ZIP, the lowest mean. West Ann Arbor’s mix of households, campus-adjacent mail, and small itemized gifts can produce that shape. The packet does not prove the mix. It publishes two numbers. It does not publish a unique-donor count.

One hundred six thousand sixty-seven contributions is a line count, not a headcount of Ann Arbor. Repeat gifts, payroll-style itemizations, and redesignations can inflate the list. Quote 106,067 as a contribution-line total.

LobbyVault does not attach a university-town political identity to $17,838,412. The source is FEC.gov receipts tagged 48103.

West-side Ann Arbor is not the whole city

48103 covers west Ann Arbor and adjoining Scio Township addresses. Other Ann Arbor ZIPs are separate keys. A committee that lists a 48103 suite still posts that code. $17,838,412 follows the form. It is not a resident-only book and not a citywide sum.

Named receipts on the ZIP 48103 FEC page are the way to see which committees appear. This guide will not invent a split inside 106,067 lines.

What the long list still excludes

Unitemized federal gifts sit outside $17,838,412. Michigan state-office campaigns sit outside. Independent expenditures paid from another ZIP sit outside even if they mention a Washtenaw race.

A long line list can hide a few large restated transfers. Recheck the live hub after quarterly filings. This prose is a snapshot of FEC.gov aggregates indexed on LobbyVault.

A contributor who gives twice is two lines. Leave 106,067 as a contribution-line count. Subtracting duplicates without a documented match key would manufacture a different total.

West Ann Arbor’s 48103 key is the volume outlier in this remaining set: 106,067 lines against $17,838,412, about $168 per line. That is many small itemized rows. It is not 106,067 unique people. Repeat gifts dominate high-volume ZIPs. This packet has no unique-donor count. Quote the line count as a line count.

Washtenaw County local campaigns never enter this federal roll-up. Recheck the ZIP 48103 FEC page after quarterly filings. Other Ann Arbor keys have their own totals in the all-ZIP directory. Named receipts show which committees appear. FEC.gov remains the original filing if the snapshot and a later file disagree.

48103 versus 48104 and 48105

Central and northeast Ann Arbor are different mail keys. Adding them to 48103 and calling the sum a city FEC total is a recode you must document. This page reports $17,838,412 for 48103 only.

The all-ZIP directory is the inventory for that comparison. Compare 106,067 against those peers rather than against a Key Biscayne ZIP with 24,000 lines. Filing shape is local to how addresses were entered.

How to read a high-volume hub

The ZIP 48103 FEC page holds $17,838,412 and 106,067 as currently indexed. The all-ZIP directory places the code among others. The donor directory lists names on itemized receipts. If a later extract disagrees, FEC.gov controls.

Filtering the donor directory to 48103 should reconcile to the ZIP hub. When a name search and 106,067 disagree, the ZIP roll-up is the geographic total. The $168 mean is arithmetic, not a typical-person gift.

Filing shape: extreme volume, low mean

West Ann Arbor appears on FEC Schedule A as ZIP 48103. The indexed total is $17,838,412 across 106,067 contributions. That extreme-volume, low-mean pattern is the fact the two numbers support. It is not a ranking of civic virtue and not a party split.

Use the ZIP 48103 FEC page as the live table. If an extract later prints a different dollar figure, the Commission’s filing wins. This prose will not silently rewrite 106,067.

48103 posts $17,838,412 across 106,067 contributions, about $168 per line. That is the longest list in this remaining-ZIP wave.

Quote 106,067 as a line count.

48104 and 48105 are other Ann Arbor keys. Adding them to 48103 manufactures a city figure. If you need that figure, list every ZIP. Keep 106,067 as the 48103 line count. The all-ZIP directory is the inventory.

Michigan state filings sit outside $17,838,412. Unitemized federal gifts sit outside. A long list can hide a few large restated transfers. Recheck the ZIP 48103 FEC page after quarterly filings.

Questions

How much federal campaign money is tied to ZIP 48103?

FEC.gov itemized receipts listing contributor ZIP 48103 total $17,838,412 across 106,067 contributions in the LobbyVault aggregate. That figure is a ZIP roll-up of federal Schedule A rows, not a unique-donor count and not a census of Ann Arbor residents. Unitemized gifts sit outside it. The mean of about $168 is arithmetic from those two packet facts.

Why does ZIP 48103 have more than 100,000 contribution lines?

LobbyVault counts 106,067 itemized contributions for ZIP 48103 against $17,838,412. Dense household mail and many small itemized gifts can produce a long list at a low mean. Repeat gifts add lines without adding unique people. This packet does not publish a unique-donor figure, so 106,067 should not be quoted as a population.

Does ZIP 48103 cover all of Ann Arbor?

No. 48103 is the west-side mail key. Other Ann Arbor ZIPs are separate roll-ups. Committees and office addresses that file 48103 can be part of $17,838,412. LobbyVault does not recode the field into a citywide or residential-only book. Open named receipts on the ZIP hub to see which committees appear.
