We recently became aware of the fact that the age groups in the Statewide Database registration datasets are using incorrect labels. The age groups are labeled 18-24, 25-34, 35-44, 45-54, 55-64 and 65 Plus when they should be labeled 18-23, 24-33, 34-43, 44-53, 54-63 and 64 Plus. All datasets back to 2002 are affected. Because most frequently age groups are used that break at -24, -34, etc. we have decided to re-run the affected datasets to adhere to this custom. We will post a note here as soon as this project is complete and the files have been replaced.
