rebin_ages: Rebin a population table to a set of age groups

Description

Rebins a population table to the coarser age groups defined by age_limits, summing populations into each group. Errors if age_limits are finer than the population data, since splitting a band would require assuming a within-band age distribution. Operates on an age column of age-group labels (e.g. from limits_to_age_groups() or assign_age_groups()) and returns the same form.

To align a population to a contact matrix's groupings for the post-processing functions, use align_ages() instead.

Usage

rebin_ages(pop, age_limits)

Value

a data frame with an age column of age-group labels and a population column

Arguments

pop

a data frame with an age column of age-group labels and a population column

age_limits

lower age limits of the (coarser) age groups to rebin to

Examples

it_pop <- data.frame(
  age = limits_to_age_groups(seq(0, 80, by = 5), notation = "brackets"),
  population = c(rep(2.5e6, 4), rep(3.5e6, 4), rep(5e6, 6), 5e6, 7e6, 4e6)
)
# rebin into 10-year age groups
rebin_ages(it_pop, age_limits = seq(0, 100, by = 10))
