Standard populations, often referred to as standard millions, are the age distributions used as weights to create age-adjusted statistics. Files containing standard population data for use in statistical software are available below. These contain the same data distributed with the SEER*Stat software. SEER also provides U.S. Population Data which can be used for analyses with SEER*Stat or other software.
Starting with the November 2004 SEER submission of data (diagnoses through 2002), the SEER Program age-adjusts using the 2000 U.S. standard population based on single years of age from the Census P25-1130 (PDF)1 series estimates of the 2000 U.S. population. For the 5-year age groups, the single year of age populations are summarized from the five single-year of age populations. See 2000 U.S. Standard Population vs. Standard Million for more discussion.
Standard Population Files
The standard population data files contain the following data:

2 The labels for these standards were updated on November 1, 2012 to clarify which standards they correspond to, but the data did not change. Documentation for the standards are in the World Health Organization's publication, Discussion Paper 31: Age Standardization of Rates: A New WHO Standard (PDF)
