Standard Populations (Millions) for Age-Adjustment

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 US 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 US standard population based on single years of age from the Census P25-1130 (PDF) ¹ series estimates of the 2000 US 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 US Standard Population vs. Standard Million for more discussion.
