Northbrook, IL political money — 2010 cycle

What the Northbrook × 2010 overlap is

Two filters produce $187,475. Filter one is donor city NORTHBROOK in IL. Filter two is FEC cycle 2010. 94 itemized rows survive both filters. $32,678,132 is the city dimension with the year filter removed. Divide $187,475 by $32,678,132 and 2010 is 0.57% of the Northbrook, IL stack; $32,490,657 (99.4%) sits in other cycles.

The Northbrook, IL hub still lists every cycle. The 2010 hub still lists every city. Citing either hub as if it were this page misstates the denominator. 94 contribution records and $187,475 are the intersection only. A city string is an address field, not a map of Illinois campaigns. Recipients can file anywhere in the FEC system.

Northbrook is stored as its own Illinois city string; Chicago and Glenview are not recoded into NORTHBROOK. Cycle 2010 is tagged as a midterm window on FEC.gov. Presidential versus midterm is a calendar label on the cycle, not a finding about Northbrook turnout or ideology. Unitemized gifts below the itemization threshold are omitted from $187,475. Independent expenditures and committee transfers are other files. Source: FEC.gov.

What the Northbrook city aggregate includes

$32,678,132 is the Northbrook, IL city book in this extract — every cycle, every employer string, so long as the city field stored NORTHBROOK. $187,475 is already inside that book. Adding $187,475 to $32,678,132 would double-count the 2010 slice. $32,490,657 is the portion of the city book filed outside 2010.

Illinois pages still include other cities. The Northbrook hub still includes other years. This join keeps both nouns in the sentence: Northbrook, IL and 2010. Northbrook is stored as its own Illinois city string; Chicago and Glenview are not recoded into NORTHBROOK. Donor city is an address on the individual receipt, not the location of the committee and not a Census place recode.

What cycle 2010 contributes to this page

2010 is a midterm even-year FEC cycle. Inside it, Northbrook, IL shows 94 itemized individual contribution records totaling $187,475. Mean row size is about $1,994 ($187,475 / 94). That ratio uses only the two join numbers. It is not household income, not a typical check, and not a unique-person average.

The 2010 election-cycle hub mixes Northbrook with every other donor city. This page does not. If a citation needs Northbrook in 2010, use this tie. If a citation needs all of 2010 nationally, use the cycle hub. If a citation needs all of Northbrook across years, use the city hub. Three different denominators.

How large 2010 is inside the Northbrook stack

$187,475 ÷ $32,678,132 = 0.57%. $32,490,657 ÷ $32,678,132 = 99.4%. Those identities use the packet's city total and cycle total only. They do not use 94 except as a separate row count. Do not convert 94 into a percentage of citywide rows; the citywide row count is not here.

A 0.57% dollar share means most of the NORTHBROOK book in this extract sits in other cycles ($32,490,657). That is a description of this table, not a claim that 2010 was quiet or loud in Northbrook politics. Other cycles are not itemized on this page.

Rows are not unique donors

94 is a contribution-record count. $187,475 is a dollar sum. $1,994 is their ratio. None of those is a unique-donor count. None is a median. None is a party split. The packet did not include those fields, so this page does not publish them.

Omitted from $187,475: unitemized individual gifts, independent expenditures, PAC transfers, and non-individual sources. Omitted from the city comparison: any city other than NORTHBROOK. Omitted from the cycle comparison: any year other than 2010, except as the $32,490,657 complement inside the same city label.

What this join does not prove

Cite the join with both sides: Northbrook, IL and the 2010 election cycle. Dropping either side turns $187,475 into a hub number it is not. 94 itemized contributions and a mean near $1,994 stay attached to that pair. $32,678,132 is the city book, not the join.

FEC individual contributions are not USAspending awards. This packet has no obligation dollars. Do not add $187,475 to federal spending in Illinois. Campaign receipts and federal awards are different statutes even when both mention Northbrook.

Use the city hub for the all-cycle total and this tie page for the 2010 slice only. Unitemized gifts are omitted from both totals.

Did Northbrook, IL 2010 donations stay in Illinois?

Not necessarily. Donor city is Northbrook, IL; recipients can be committees anywhere that file with the FEC. This join does not allocate the $187,475 by office, state of the committee, or party. An IL city code is an address field on the individual receipt, not a map of Illinois races or of where the money was spent.
