Preliminary death data are available for years in which death records for Oklahoma residents are still in the collection process. These statistics are subject to change and are available, based on user-specified criteria, as either a table with frequencies or a cross-tabulation. In addition to queries that are user-defined, standard tables are available for a large variety of topics.

The National Center for Health Statistics has discontinued the postcensal bridged-race population estimates (used for calculating rates) with the release of the Vintage 2020 estimates. Starting with 2021 death statistics, OK2SHARE will display the racial categories used by the U.S. Census Bureau - White, Black, American Indian, Asian, Native Hawaiian and Pacific Islander, and Two or more races. Hispanic Origin did not change.
