National Center for Health Statistics Mortality Surveillance System
The National Center for Health Statistics (NCHS) collects and disseminates the Nation's official vital
statistics. NCHS collects death certificate data from state vital statistics offices for virtually all deaths
occurring in the United States. Pneumonia and influenza (P&I) deaths are identified based on ICD-10
multiple cause of death codes.
About the Data
NCHS Mortality Surveillance System data are presented by the week the death occurred at the
national, state, and HHS Region levels. Data on the percentage of deaths due to P&I on a national level
are released two weeks after the week of death to allow for collection of enough data to produce a
stable percentage. States and HHS regions with less than 20% of the expected total deaths (average
number of total deaths reported by week during 2008-2012) will be marked as insufficient data.
Collection of complete data is not expected at the time of initial report, and a reliable percentage of
deaths due to P&I is not anticipated at the U.S. Department of Health and Human Services region or
state level within this two week period. The data for earlier weeks are continually revised and the
proportion of deaths due to P&I may increase or decrease as new and updated death certificate data
are received by NCHS.
