As part of the preparation process for the 2020 City of Chicago budget, the City conducted a public survey. The final results are shown in this dataset.

For the $1000 Assignment columns, negative values have been converted to blanks and totals above $1000 (after converting negatives to blanks) have been converted to $1000, with all of the component values adjusted accordingly, to retain their relative proportions. Totals below $1000 were not adjusted up because the survey specifically allowed for not allocating the full amount.

NOT CURRENT DATA - This dataset contains past records from the Public Chauffeurs dataset. It is intended for historical reference, not current licensing information. It follows the format of the Public Chauffeurs dataset, with the addition of two additional columns at the end.

The Last Valid Date column indicates the most recent timestamp when that set of values appeared in the Public Chauffeurs dataset. It indicates when that version of the license record stopped being valid (was replaced by an updated version), not when it started being valid (replaced a previous version or was created for a newly added license). Due to various technical limitations, the Last Valid Date may be artificially late and intervening versions not shown are possible.

The Record Version ID is a unique identifier that has no meaning beyond distinguishing different versions of the same license.

Please read the article linked below for more information.

Due to a change in source systems, many licenses will appear to have changed on 11/21/2018, even if no actual change to the license took place. Some records between 11/19/2018 and 11/21/2018 may be unreliable and should be used with caution. The Expires column was added with the move to the new source system so will not appear in earlier records.

OUTDATED. See the current data at https://data.cityofchicago.org/d/kjav-iyuj -- Special Service Areas (SSA) boundaries in Chicago. The Special Service Area program is a mechanism used to fund expanded services and programs through a localized property tax levy within contiguous industrial, commercial and residential areas. The enhanced services and programs are in addition to services and programs currently provided through the city. SSA-funded projects could include, but are not limited to, security services, area marketing and advertising assistance, promotional activities such as parades and festivals, or any variety of small scale capital improvements that could be supported through a modest property tax levy.

List of sites that guarantee specific, non-flu vaccines will be in-stock and available for the time period indicated in each record. For flu shot locations, go to https://data.cityofchicago.org/Health-Human-Services/Flu-Shot-Locations-2014-Present/w3hg-pyhz.

Note for using this dataset that it is always recommended that individuals contact their healthcare provider or closest pharmacy to check on vaccine availability prior to walking in for vaccination. Each vaccine has a filtered view showing only records from that vaccine and blank filter conditions that can be used to filter further by time. These filtered views can be used for almost all purposes as if they were datasets, although any additional criteria added by a user would need to be saved to a new filtered view in order to use it in this manner. This dataset approximately follows https://github.com/codeforamerica/flu-shot-spec/blob/master/data-format.csv and is designed for use by https://github.com/tkompare.
