The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Block Groups (BGs) are clusters of blocks within the same census tract. Each census tract contains at least one BG, and BGs are uniquely numbered within census tracts. BGs have a valid code range of 0 through 9. BGs have the same first digit of their 4-digit census block number from the same decennial census. For example, tabulation blocks numbered 3001, 3002, 3003,.., 3999 within census tract 1210.02 are also within BG 3 within that census tract. BGs coded 0 are intended to only include water area, no land area, and they are generally in territorial seas, coastal water, and Great Lakes water areas. Block groups generally contain between 600 and 3,000 people. A BG usually covers a contiguous area but never crosses county or census tract boundaries. They may, however, cross the boundaries of other geographic entities like county subdivisions, places, urban areas, voting districts, congressional districts, and American Indian / Alaska Native / Native Hawaiian areas. The BG boundaries in this release are those that were delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2010 Census.

Utilizing data from multiple sources, including the Behavioral Risk Factor Surveillance System (BRFSS) from 2021 and 2020, Census Bureau's population estimates for census tracts from 2021 to 2016, and American Community Survey (ACS) estimates covering the years 2017 to 2016, this dataset offers a robust foundation for analyzing health trends at the census tract level. It serves as a valuable resource for public health officials, researchers, and policymakers aiming to understand and address health disparities and challenges within Oklahoma's diverse communities.For a comprehensive understanding of the data variables, please refer to the following link: Google Sheets.

It includes various parameters such as temperature, humidity, dewpoint, vapor deficit, air pressure, wind speed, solar radiation, and soil temperature. Each parameter is averaged over specific time intervals (e.g., 5-minute, 15-minute) and provides a comprehensive overview of daily weather and environmental conditions.The Mesonet stations require a minimum percentage of observations for the day to be included in daily calculations. For instance, total daily solar radiation is calculated only if 99% of the observations for the site and day are available. Other parameters, such as maximum wind gust, maximum heat index, and minimum wind chill, require at least one observation to be recorded for the day. Wind direction data are only recorded when wind speeds exceed 2.5 mph, and most other variables require at least 90% of the observations to be computed.This dataset is essential for researchers, policymakers, and agricultural professionals, providing critical data to analyze environmental trends, assess climate patterns, and make informed decisions related to agriculture and environmental management.
