demoSynthPop

The original goal of demoSynthPop is to recreate the ETHPOP population data using the ETHPOP birth, death, inmigration and outmigration data. This is a check for internal consistency and we will use the same approach to extend for UK born and non-UK born individuals too.

Installation

You can install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("ETHPOP-and-ETS/demoSynthPop")

Input data

ETHPOP data can be downloaded from here.

The ETHPOP data are:

• Births by year, for ethnic group and sex
• Deaths by year, for ethnic group, sex and age
• In-migration by year, for ethnic group, sex and age
• Out-migration by year, for ethnic group, sex and age

The ethnic groups are: BAN (Bangladeshi), BLA (Black African), BLC (Black Caribbean), CHI (Chinese), IND (Indian), MIX (Mixed), OAS (Other Asian), OBL (Other Black), OTH (Other), PAK (Pakistani), WBI (White British), WHO (White Other)

The ages are individual years from 0 to 99 and a single group for $\geq$ 100.

The calendar years are 2011 to 2061.

Example

The main analysis is in main.R and uses the run_model() function. This loops over each year performing the 'demographic arithmetic' of removing and adding individuals according to the ETHPOP tables.

There are two ways in which we can do this:

• Absolute population counts: analysis here.
• Per-capita proportions: analysis here.

The algorithm in run_model() takes the following steps:

1. Age the population by one year, using age_population().
2. Include new births at age 0, using add_births().
3. Remove individuals due to mortality, using add_deaths().
4. Include in-migrants, using add_inflow().
5. Remove individuals due to out-migration, using add_outflow().
