OAK BROOK, IL: $27.5M on 34,550 FEC receipts

Fewer lines on a $27.5 million book

Thirty-four thousand five hundred fifty lines produce $27,513,396. Divide the pair and the mean itemized line is about $796. That mean is arithmetic from the two packet facts. It is not a typical household gift. FEC.gov does not publish a median on this city aggregate.

Hinsdale, Oak Brook Terrace, and Elmhurst keep separate Illinois hubs when those strings appear. They are not inside $27,513,396 unless the filer typed OAK BROOK. DuPage County is orientation, not an FEC roll-up.

Oak Brook, not Oak Brook Terrace

Oak Brook Terrace is a different city string. This packet publishes OAK BROOK, IL only: $27,513,396 and 34,550 lines. Folding the two names would be a recode.

State IL on the key is required in the citation. Recheck both facts on the live hub if a later extract lands.

City field versus postal map

FEC.gov stores whatever city appeared on the itemized receipt. OAK BROOK plus IL is the match. Recoding into a Census place or a Chicago metro label is a different dataset.

ZIP pages cut the same federal series by postal code. Summing western-suburb ZIPs can diverge from $27,513,396 when some receipts used Hinsdale or Elmhurst as the city. The 34,550-line count follows the city field.

Limits of the Oak Brook aggregate

Illinois state campaigns file under state law. Those receipts are outside $27,513,396 and outside 34,550. Unitemized federal gifts are omitted. Independent expenditures that never appear as contribution itemizations are outside both facts.

Nothing here estimates how Oak Brook voted. Occupation and recipient live on other FEC fields. Use the city table, then ZIP pages, then the cities index.

Citing OAK BROOK, IL

Name FEC.gov, name contributor city, and print $27,513,396 with 34,550 together. Dropping the line count hides why the mean sits near $796.

Office addresses can share the Oak Brook city field with household streets. Totals can include a PAC or joint-fundraising address when that is what filers typed. The 34,550 lines are receipts, not unique persons. If the live hub disagrees with this snapshot, trust the hub. Open original reports on FEC.gov when a named Oak Brook receipt matters.

How researchers should use the Oak Brook hub

Start on the live Oak Brook city page, then open ZIP pages if a postal cut is the real question. $27,513,396 is the city-string dollar total in this snapshot. 34,550 is the matching line count. Those two numbers move together when FEC.gov amends a receipt. They do not move because a researcher prefers Hinsdale as the “real” neighbor. Filers typed OAK BROOK. LobbyVault indexed OAK BROOK.

A mean near $796 is only $27,513,396 divided by 34,550. The relatively small line count is the shape of this extract. Occupation, recipient, and party are different FEC fields. None of those fields are in this packet. Cite the pair: contributor city OAK BROOK, IL, $27,513,396, 34,550 itemized federal contributions, source FEC.gov via LobbyVault. Illinois non-federal filings never enter either fact.

Oak Brook Terrace is a different municipal name. Rows typed that way never enter $27,513,396. The 34,550 lines are OAK BROOK only. Hinsdale and Elmhurst keep separate hubs. The mean near $796 follows from a smaller line count on a $27.5 million book.

DuPage County is orientation, not a roll-up. Illinois non-federal filings stay outside. Cite OAK BROOK, IL with both packet facts. Recheck the live hub. Unitemized gifts stay outside. Original reports remain on FEC.gov for any named Oak Brook receipt.

Oak Brook’s 34,550 lines on $27,513,396 put the mean near $796. Oak Brook Terrace is a different municipal string. Hinsdale is a different hub. DuPage County is orientation. Illinois state filings stay outside. Cite OAK BROOK, IL with both packet facts. Recheck the live hub. Repeat gifts can add rows without adding donors. Unique donors are unpublished. Original reports remain on FEC.gov.

Keep OAK BROOK, IL, $27,513,396, and 34,550 in one citation. The mean near $796 is those two numbers divided. Oak Brook Terrace remains a separate string. Hinsdale remains a separate string. DuPage County remains a map. Illinois non-federal filings remain outside. Unitemized federal gifts remain outside. Independent expenditures that are not contribution itemizations remain outside. Start on the live city page. Open ZIP pages for a postal cut. Open FEC.gov for a named Oak Brook receipt that needs the original filing.

Questions

What is Oak Brook’s federal contribution total on LobbyVault?

Itemized FEC.gov receipts listing contributor city OAK BROOK, IL total $27,513,396 across 34,550 contributions. That pair is a city-string roll-up of federal Schedule A rows, not a unique-donor count and not a census of Oak Brook residents. Unitemized gifts sit outside both figures.

Why is Oak Brook’s mean near $796?

Divide $27,513,396 by 34,550 and the arithmetic mean is about $796. The line count is smaller than on many $27 million city hubs. That is a shape fact, not a typical gift. This packet publishes no unique-donor figure and no median.

Does Oak Brook’s total include Hinsdale or Oak Brook Terrace?

Only if the filer typed OAK BROOK. Hinsdale, Oak Brook Terrace, and Elmhurst are separate city strings when they appear that way on the receipt. $27,513,396 is the OAK BROOK, IL match. The 34,550 lines follow the same rule. DuPage County is not an FEC dimension on this hub.

Where do the Oak Brook facts come from?

Both facts come from FEC.gov itemized contribution aggregates indexed on LobbyVault: $27,513,396 and 34,550 lines. Original reports remain on FEC.gov. Illinois non-federal filings are outside the pair. If a later extract disagrees, the Commission’s filing controls. The mean of about $796 is arithmetic from those two packet numbers.
