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 = NULL,
  pop_age_column = "lower.age.limit",
  pop_column = "population",
  ...,
  age.limits = deprecated(),
  pop.age.column = deprecated(),
  pop.column = deprecated()
)

Value

data frame of age-specific population data

Arguments

pop

a data frame with columns indicating lower age limits and population sizes (see 'pop_age_column' and 'pop_column')

age_limits

lower age limits of age groups to extract; if NULL (default), the population data is returned unchanged

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

age.limits, pop.age.column, pop.column

Use the underscore versions (e.g., age_limits) instead.

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_limits = seq(0, 100, by = 10))

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