Jefferson Park Crime Map

A repeatable count, not a scored ranking

1,550 is what you get if you take the indexed CPD extract and keep the rows assigned to Jefferson Park. There is no seriousness score, no extra weight for certain IUCR codes, and no subtraction of reports that later went nowhere in court. Repeatability is the point. Another person with the same extract and the same community-area filter should land on the same 1,550.

Repeatable does not mean complete in every moral sense. It means complete relative to the published file. Reports that CPD never released, or released with a different area assignment, are outside the 1,550 by definition. Cite the number as an indexed open-data total. Then send anyone who needs the wording on a single event to the incident table rather than to this headline.

Jefferson Park as a fraction of 410,083

1,550 is about 0.38 percent of 410,083 citywide reports, or about one in 265 published rows. A percentage that small is still more than a thousand records. Citywide denominators shrink every community area; they do not erase the local file. Report both numbers. A chart that shows only the percentage hides 1,550. A chart that shows only 1,550 hides Chicago.

This packet has no population, so 0.38 percent of reports is not a rate per resident. It also has no date span, so the share is not this year’s share. It is the share of this extract. The Chicago crime hub is the parent page for the 410,083. Use it when you need the rest of the file, not a second Jefferson Park total.

Questions

How many CPD reports are indexed for Jefferson Park?

Jefferson Park has 1,550 Chicago Police Department incident reports in this index, inside a citywide file of 410,083 records from the open-data portal. The figure counts published reports assigned to the community area. It does not count convictions. Read the incident table for CPD’s published fields on each row rather than inferring an offense mix from the headline.

What share of Chicago’s file is Jefferson Park?

1,550 is about 0.38 percent of 410,083 citywide CPD reports, or about one in 265 rows. That is a share of this extract, not a per-capita rate. Population is not in the packet, so a rate is not computed here.

Are Jefferson Park’s 1,550 reports the same as court cases?

No. They are public police incident reports. Review, charging, and trial sit in other systems. This page has no conviction total because that number is not in the packet. Quote 1,550 as CPD open data for Jefferson Park. Quote the neighborhood total as public police reports from city open data, not as arrests, charges, or convictions.

Where do I open Jefferson Park’s rows and the city file?

Use the Jefferson Park incident table on the community-area overlay, or the named Jefferson Park page for the same slice. The Chicago crime hub holds the parent 410,083-report index. All three links stay in this CPD collection. Named and numbered neighborhood URLs in this index point at the same community-area extract, not at two different counts.
