The Occupational Cohort Mortality Analysis Program (OCMAP), developed at the University of Pittsburgh, is a widely distributed modularized computer program that performs many basic data management and statistical analysis procedures. While OCMAP is designed primarily for occupational mortality studies, applications generalize easily to studies of other health end-points, such as cancer incidence, and to studies in non-occupational settings (e.g., pharmaco-epidemiology). The current OCMAP program is now in use by over 300 institutions in the United States and abroad. Releases of OCMAP have been referenced in over 200 peer-reviewed journals, based on a review of the Scientific Citations Index database. More information about OCMAP can be found on the OCMAP/MPDS website here.

Since 1980, the Department of Biostatistics at the University of Pittsburgh has maintained a data repository and retrieval system for detailed mortality data provided by the National Center for Health Statistics and the US Census Bureau. This Mortality and Population Data System (MPDS) contains the underlying cause of death code (using International Classification of Diseases (ICD) four-digit codes) for all persons who died in the United States between 1950 and 2016 (limited to deaths from malignant neoplasms for the 1950-1961 period). Death records include codes for sex, race, age at death, year of death, and geographic location (county and state residence at time of death). More information about MPDS can be found on the OCMAP/MPDS website here.
