Calculate Das Gupta's (1995) age sex accuracy index

Description

Given population counts in 5-year age groups for males and females, follow Das Gupta's steps to calculate a composite index of the quality of the age and sex structure for a given population.

Usage

ageSexAccuracyDasGupta(
  Males,
  Females,
  Age,
  ageMin = 0,
  ageMax = max(Age),
  OAG = TRUE
)

Arguments

Males	numeric. A vector of demographic counts in 5-year age groups for males.
Females	numeric. A vector of demographic counts in 5-year age groups for females.
Age	numeric. A vector of ages corresponding to the lower integer bound of the counts.
ageMin	integer. The lowest age included in calculations. Default 0.
ageMax	integer. The upper age bound used for calculations. Default max(Age).
OAG	logical. Whether or not the top age group is open. Default TRUE.

Details

It is assumed that the terminal age group is open, in which case it is ignored. Set OAG = FALSE if the top age is indeed a closed interval that you want included in calculations. If ageMax == max(Age) and OAG is TRUE, then ageMax gets decremented one age class.

Females <- c(2244, 2248, 1773, 1594, 1616, 1510, 1478, 1320,
              1085, 858, 768, 726, 533, 282)
Age     <- seq(0, 65, by = 5)

# this method is not on the same scale as the others, so don't directly compare.
