uspop2: Projected US Population

In survival: Survival Analysis

Projected US Population

Description

US population by age and sex, for 2000 through 2020

Usage

uspop2

Format

The data is a matrix with dimensions age, sex, and calendar year. Age goes from 0 through 100, where the value for age 100 is the total for all ages of 100 or greater.

Details

This data is often used as a "standardized" population for epidemiology studies.

Note

The usage above assumes that the survival package is attached via library(survival) or via another package that depends on survival, e.g., mstate. If not, then either survival::uspop2 can be used or data(survexp, package="survival").
