pop_age: Change age groups in population data

Description

This changes population data to have age groups with the given age.limits, extrapolating linearly between age groups (if more are requested than available) and summing populations (if fewer are requested than available)

Usage

pop_age(
  pop,
  age.limits,
  pop.age.column = "lower.age.limit",
  pop.column = "population",
  ...
)

Value

data frame of age-specific population data

Arguments

pop

a data frame with columns indicating lower age limits and population sizes (see 'age.column' and 'pop.column')

age.limits

lower age limits of age groups to extract

pop.age.column

column in the 'pop' data frame indicating the lower age group limit

pop.column

column in the 'pop' data frame indicating the population size

...

ignored

Examples

ages_it_2015 <- wpp_age("Italy", 2015)

# Modify the age data.frame to get age groups of 10 years instead of 5
pop_age(ages_it_2015, age.limit = seq(0, 100, by = 10))

# The function will also automatically interpolate if necessary
pop_age(ages_it_2015, age.limit = c(0, 18, 40, 65))
