Land Area
Water Area
Land area is a measurement providing the size, in square miles, of the land portions of geographic entities for which the Census Bureau tabulates and disseminates data. Area is calculated from the specific boundary recorded for each entity in the Census Bureau's geographic database. Land area is based on current information in the TIGER® data base, calculated for use with Census 2010.
Water Area figures include inland, coastal, Great Lakes, and territorial sea water. Inland water consists of any lake, reservoir, pond, or similar body of water that is recorded in the Census Bureau's geographic database. It also includes any river, creek, canal, stream, or similar feature that is recorded in that database as a two- dimensional feature (rather than as a single line). The portions of the oceans and related large embayments (such as Chesapeake Bay and Puget Sound), the Gulf of Mexico, and the Caribbean Sea that belong to the United States and its territories are classified as coastal and territorial waters; the Great Lakes are treated as a separate water entity. Rivers and bays that empty into these bodies of water are treated as inland water from the point beyond which they are narrower than 1 nautical mile across. Identification of land and inland, coastal, territorial, and Great Lakes waters is for data presentation purposes only and does not necessarily reflect their legal definitions.

NCHS - Birth Rates for Females by Age Group: United States
data.cdc.gov | Last Updated 2022-03-29T11:35:59.000ZThis dataset includes birth rates for females by age group in the United States since 1940. The number of states in the reporting area differ historically. In 1915 (when the birth registration area was established), 10 states and the District of Columbia reported births; by 1933, 48 states and the District of Columbia were reporting births, with the last two states, Alaska and Hawaii, added to the registration area in 1959 and 1960, when these regions gained statehood. Reporting area information is detailed in references 1 and 2 below. Trend lines for 1909–1958 are based on live births adjusted for under-registration; beginning with 1959, trend lines are based on registered live births.

Beach Water Quality - Automated Sensors
data.cityofchicago.org | Last Updated 2024-05-30T13:45:15.000ZThe Chicago Park District maintains sensors in the water at beaches along Chicago's Lake Michigan lakefront. These sensors generally capture the indicated measurements hourly while the sensors are in operation during the summer. During other seasons and at some other times, information from the sensors may not be available. See https://data.cityofchicago.org/d/k7hf-8y75 for a dataset with land-based weather measurements at selected beaches. The sensor locations are listed at https://data.cityofchicago.org/d/g3ip-u8rb. Please note that sensor locations change with the Park District’s operational needs, primarily related to water quality. For more information on beach operations, please see https://www.chicagoparkdistrict.com/parks-facilities/beaches.

311 Service Requests - Graffiti Removal - Historical
data.cityofchicago.org | Last Updated 2019-03-07T22:13:35.000ZAs described in http://bit.ly/311HistoricalPost, the function of this dataset was replaced by https://data.cityofchicago.org/d/v6vf-nfxy. This dataset is historical-only. All open graffiti removal requests made to 311 and all requests completed since January 1, 2011. The Department of Streets & Sanitation's Graffiti Blasters crews offer a vandalism removal service to private property owners. Graffiti Blasters employ "blast" trucks that use baking soda under high water pressure to erase painted graffiti from brick, stone and other mineral surfaces. They also use paint trucks to cover graffiti on the remaining surfaces. Organizations and residents may report graffiti and request its removal. 311 sometimes receives duplicate requests for graffiti removal. Requests that have been labeled as Duplicates are in the same geographic area and have been entered into 311’s Customer Service Requests (CSR) system at around the same time as a previous request. Duplicate reports/requests are labeled as such in the Status field, as either "Open - Dup" or "Completed - Dup." Data is updated daily.
