About this dataset

Context

The dataset tabulates the Chicago population over the last 20 plus years. It lists the population for each year, along with the year on year change in population, as well as the change in percentage terms for each year. The dataset can be utilized to understand the population change of Chicago across the last two decades. For example, using this dataset, we can identify if the population is declining or increasing. If there is a change, when the population peaked, or if it is still growing and has not reached its peak. We can also compare the trend with the overall trend of United States population over the same period of time.

Key observations

In 2023, the population of Chicago was 2.66 million, a 0.31% decrease year-by-year from 2022. Previously, in 2022, Chicago population was 2.67 million, a decline of 1.16% compared to a population of 2.7 million in 2021. Over the last 20 plus years, between 2000 and 2023, population of Chicago decreased by 231,271. In this period, the peak population was 2.9 million in the year 2000. The numbers suggest that the population has already reached its peak and is showing a trend of decline. Source: U.S. Census Bureau Population Estimates Program (PEP).

Separate tables are provided for three geographic levels:The seven counties in the CMAP region (with regional total)The 284 municipalities in the CMAP regionThe 77 Chicago community areas (CCAs)There is limited geographic availability (particularly at the CCA level) for some variables. Additional information on availability and data sources are found in the CDS Data Dictionary.NOTE: Much of the data is from 5-year American Community Survey, which is a sample-based data product. This means users must exercise caution when interpreting data from low-population municipalities, as the margins of error are often large compared to the estimate.

Each record in this dataset shows information about an arrest executed by the Chicago Police Department (CPD). Source data comes from the CPD Automated Arrest application. This electronic application is part of the CPD CLEAR (Citizen Law Enforcement Analysis and Reporting) system, and is used to process arrests Department-wide.

A more-detailed version of this dataset is available to media by request. To make a request, please email dataportal@cityofchicago.org with the subject line: Arrests Access Request. Access will require an account on this site, which you may create at https://data.cityofchicago.org/signup. New data fields may be added to this public dataset in the future. Requests for individual arrest reports or any other related data other than access to the more-detailed dataset should be directed to CPD, through contact information on that site or a Freedom of Information Act (FOIA) request.

The data is limited to adult arrests, defined as any arrest where the arrestee was 18 years of age or older on the date of arrest. The data excludes arrest records expunged by CPD pursuant to the Illinois Criminal Identification Act (20 ILCS 2630/5.2).

Department members use charges that appear in Illinois Compiled Statutes or Municipal Code of Chicago. Arrestees may be charged with multiple offenses from these sources. Each record in the dataset includes up to four charges, ordered by severity and with CHARGE1 as the most severe charge. Severity is defined based on charge class and charge type, criteria that are routinely used by Illinois court systems to determine penalties for conviction. In case of a tie, charges are presented in the order that the arresting officer listed the charges on the arrest report. By policy, Department members are provided general instructions to emphasize seriousness of the offense when ordering charges on an arrest report.

Each record has an additional set of columns where a charge characteristic (statute, description, type, or class) for all four charges, or fewer if there were not four charges, is concatenated with the | character. These columns can be used with the Filter function's "Contains" operator to find all records where a value appears, without having to search four separate columns.

Users interested in learning more about CPD arrest processes can review current directives, using the CPD Automated Directives system (http://directives.chicagopolice.org/directives/). Relevant directives include:

• Special Order S06-01-11 – CLEAR Automated Arrest System: describes the application used by Department members to enter arrest data. • Special Order S06-01-04 – Arrestee Identification Process: describes processes related to obtaining and using CB numbers. • Special Order S09-03-04 – Assignment and Processing of Records Division Numbers: describes processes related to obtaining and using RD numbers. • Special Order 06-01 – Processing Persons Under Department Control: describes required tasks associated with arrestee processing, include the requirement that Department members order charges based on severity.

Dataset Description

Authors: Ludovic Moncla, Katherine McDonough and Denis Vigier in the framework of the GEODE project. Data source: ARTFL Encyclopédie Project, University of Chicago Github repository: https://github.com/GEODE-project/ner-spancat-edda Language: French License: cc-by-nc-4.0 Zenodo repository: https://zenodo.org/records/10530177

Dataset Summary This dataset contains semantic annotations (at the token and span levels) for named entities (such as Spatial, Person, and MISC), nominal entities, as well as nested named entities, spatial relations, and other relevant information within French encyclopedic entries.

The span tagset is as follows: - NC-Spatial: a common noun that identifies a spatial entity (nominal spatial entity) including natural features, e.g. ville, la rivière, royaume. - NP-Spatial: a proper noun identifying the name of a place (spatial named entities), e.g. France, Paris, la Chine. - ENE-Spatial: nested spatial entity , e.g. ville de France, royaume de Naples, la mer Baltique. - Relation: spatial relation, e.g. dans, sur, à 10 lieues de. - Latlong: geographic coordinates, e.g. Long. 19. 49. lat. 43. 55. 44. - NC-Person: a common noun that identifies a person (nominal spatial entity), e.g. roi, l'empereur, les auteurs. - NP-Person: a proper noun identifying the name of a person (person named entities), e.g. Louis XIV, Pline, les Romains. - ENE-Person: nested people entity, e.g. le czar Pierre, roi de Macédoine - NP-Misc: a proper noun identifying entities not classified as spatial or person, e.g. l'Eglise, 1702, Pélasgique. - ENE-Misc: nested named entity not classified as spatial or person, e.g. l'ordre de S. Jacques, la déclaration du 21 Mars 1671. - Head: entry name - Domain-Mark: words indicating the knowledge domain (usually after the head and between parenthesis), e.g. Géographie, Geog., en Anatomie.

Supported Tasks

token-classification or span-classification: The dataset can be used to train a model for token-classification or span-classification. It is more specifically designed for spatial role labelling. A spacy custom spancat model is available at: https://huggingface.co/GEODE/fr_spacy_custom_spancat_edda.

Dataset Structure The dataset is provided as JSONL files¹ where each row follows the following structure:

{ "text": "ILLESCAS, (Géog.) petite ville d'Espagne <...> ", "meta": {"volume": 8, "head": "ILLESCAS", "author": "unsigned", "domain_article": "Géographie", "domain_paragraph": "Géographie", "article": 2637, "paragraph": 1}, "tokens": [{"text": "ILLESCAS", "start": 0, "end": 8, "id": 0, "ws": false}, {"text": ",", "start": 8, "end": 9, "id": 1, "ws": true}, {"text": "(", "start": 10, "end": 11, "id": 2, "ws": false}, {"text": "Géog", "start": 11, "end": 15, "id": 3, "ws": false}, {"text": ".", "start": 15, "end": 16, "id": 4, "ws": false}, {"text": ")", "start": 16, "end": 17, "id": 5, "ws": true}, {"text": "petite", "start": 18, "end": 24, "id": 6, "ws": true}, {"text": "ville", "start": 25, "end": 30, "id": 7, "ws": true}, {"text": "d'", "start": 31, "end": 33, "id": 8, "ws": false}, {"text": "Espagne", "start": 33, "end": 40, "id": 9, "ws": false}, {"text": ",", "start": 40, "end": 41, "id": 10, "ws": true} <...>], "spans": [{"text": "ILLESCAS", "start": 0, "end": 8, "token_start": 0, "token_end": 0, "label": "Head"}, {"text": "Géog.", "start": 11, "end": 16, "token_start": 3, "token_end": 4, "label": "Domain-mark"}, {"text": "petite ville", "start": 18, "end": 30, "token_start": 6, "token_end": 7, "label": "NC-Spatial"}, {"text": "petite ville d'Espagne", "start": 18, "end": 40, "token_start": 6, "token_end": 9, "label": "ENE-Spatial"}, {"text": "petite ville d'Espagne, dans la nouvelle Castille", "start": 18, "end": 67, "token_start": 6, "token_end": 14, "label": "ENE-Spatial"}, {"text": "Espagne", "start": 33, "end": 40, "token_start": 9, "token_end": 9, "label": "NP-Spatial"}, <...>] }

Each data contains four main fields:

text: plain text of a paragraph. meta: metadata from the ARTFL Encyclopédie about the paragraph such volume, article, paragraph id, headword, etc. tokens: list of tokens, with their text, id, start and end position at the character level. spans: list of spans (i.e., annotations), with their text, label, start and end position at the character level.

spaCy binary files are also available on the Github and Zenodo repositories.

Data Splits The dataset consists of 2200 paragraphs randomly selected out of 2001 Encyclopédie's entries. All paragraphs were written in French and are distributed as follows among the Encyclopédie knowledge domains:

The spans/entities were labeled by the project team along with using pre-labelling with early models to speed up the labelling process. A train/val/test split was used. Validation and test sets are composed of 200 paragraphs each: 100 classified as 'Géographie' and 100 from another knowledge domain. The datasets have the following breakdown of tokens and spans/entities.
