The purpose of the Birth module is to generate interactive statistics of birth certificate data. The intended audience is researchers, public health officials, students, and the general public. The data originates from the birth certificate. Users can select year, maternal race, maternal age, marital status, region, and birth characteristic as row or column variables. Using the drop down boxes can further restrict these same variables. A list of all the birth characteristics can be found in the definitions page. Users can further sort the output by region, whether alphabetically or numerically. Users can generate on-the-fly maps and tables of the frequencies, rates, and percentages of the selected data. Rates cannot be calculated at the zip code level due to the lack of census data. All rates are calculated per 1000 annual live births. When rates have been selected 95% and 99% Confidence intervals can also be generated in the tables. The interpretation of tables and maps is the users responsibility. Thorough labels are provided however to make interpretation more intuitive. Many supporting pages are provided with definitions, examples of rate calculations, Division of Biostatistics and Health GIS contact information, and frequently asked questions to assist the user in interpreting this data. Rates with small numbers are unreliable and should be used cautiously.
