Methodology and Assumptions for the 2012 National Projections.

摘要

The U.S. Census Bureau periodically produces projections of the United States resident population by age, sex, race, and Hispanic origin. These projections are produced using a cohort-component method and are based on assumptions about demographic components of change (future births, deaths, and net international migration). This document presents the methodology and assumptions used to produce the 2012 National Projections . the first based on the 2010 Census . for 2012 through 2060.
