inedemogR

CRAN status CRAN downloads

inedemogR provides tidy access to demographic data from the Spanish National Statistics Institute (INE), specifically its “fenómenos demográficos” domain: population, births, and deaths. Data is retrieved live via the official ineapir API wrapper and tidied into long/wide data frames, with optional spatial integration via mapSpain and sf.

Installation

Install the released version from CRAN with:

install.packages("inedemogR")

Version 0.2.0 corrects numerical errors in 0.1.0 (the Andreev-Kingkade a0, old-age smoothing, the ESP 2013 weights, abridged tables, the Pollard decomposition, fertility conventions and missing-data handling); see NEWS.md. Results computed with 0.1.0 should be recomputed with 0.2.0 or later. Version 0.2.1 adds input checks to the abridged life tables and the optional cohort-based exposure.

You can install the development version of inedemogR from GitHub with:

# install.packages("pak")
pak::pak("jrcarob/inedemogR_package")

or

# install.packages("devtools")
devtools::install_github("jrcarob/inedemogR_package")

Example

library(inedemogR)

# List available indicators and the INE tables they're wired to
list_ine_indicators()

# Fetch population data for municipalities in 2023 (real INE data)
pop_data <- get_ine_demog(indicator = "population_total", year = 2023)

# Fetch births and deaths by province in the same call
vital_stats <- get_ine_demog(
  indicator = c("births_total", "deaths_total"),
  year = 2023
)

# Fetch the same population data with geometries attached
pop_sf <- get_ine_demog(
  indicator = "population_total",
  year = 2023,
  region = "^Sevilla$",
  geometry = TRUE
)

Indicators are only available at the geographic level their source INE table is actually published at: population_total is municipality-level, births_total/deaths_total are province-level. Requesting indicators that span different levels in one call raises an error rather than silently mixing granularities — see list_ine_indicators().

Two workflows

inedemogR supports two deliberately parallel, complementary workflows — neither subsumes the other, since they operate at different geographic and demographic granularities.

Workflow (a): export and work with files. download_ine_data() runs the province-level SHMD mortality pipeline (births, deaths, population, exposure-to-risk, central death rates, period life tables, per HMD Methods Protocol V6) and writes the results to a folder as CSV and/or HMD-format .txt files, for use outside R:

download_ine_data("ine_data")

Workflow (b): stay in R. For quick multi-geo-level choropleths of total counts, use get_ine_demog()/get_ine_geo()/plot_ine_map() (see the example above). For age-structured demographic analysis — dependency ratios, aging index, sex ratio, population pyramids, life expectancy — use the province-level, age/sex-disaggregated functions behind download_ine_data() directly:

pop <- get_ine_population()

# Summary indicators (one row per province x year)
age_dependency_ratio(pop$data)
aging_index(pop$data)
sex_ratio(pop$data)

# Charts
plot_population_pyramid(pop$data, year = max(pop$data$year), region = "A Coruna")

# Life expectancy: full pipeline through life tables, then map it,
# bridging this province-level analysis back onto get_ine_geo()'s
# spatial layer
deaths <- get_ine_deaths()
exposure <- compute_exposure(pop$data, deaths$data_provinces)
rates <- compute_death_rates(deaths$data_provinces, exposure$data)
lt <- build_life_tables(rates$mx_1x1)
le <- life_expectancy_summary(lt$fltper, sex = "female")
map_life_expectancy(le, year = max(le$year), sex = "female")

Note crude_birth_rate() computes a crude birth rate (births/population), not a total fertility rate. For a true TFR, use get_ine_births_by_age() (age-of-mother birth counts) with age_specific_fertility_rate()/total_fertility_rate():

births_age <- get_ine_births_by_age()
asfr <- age_specific_fertility_rate(births_age$data, pop$data)
total_fertility_rate(asfr)

Status

inedemogR is under active development. System A (get_ine_demog(), get_ine_geo(), list_ine_indicators(), plot_ine_map()) implements live retrieval and mapping of municipality/province-level total counts. Migration indicators are not included in this release. System B (get_ine_births()/get_ine_deaths()/get_ine_population(), compute_exposure(), compute_death_rates(), build_life_tables(), download_ine_data()) implements a province-level, age/sex-disaggregated SHMD mortality pipeline, with summary indicators (age_dependency_ratio(), aging_index(), sex_ratio(), crude_birth_rate(), life_expectancy_summary()) and charts (plot_population_pyramid(), plot_demog_trend(), map_life_expectancy()) built on top. A comprehensive tutorial covering every function, the mortality-pipeline mathematics, and full worked examples is available via vignette("inedemogR-tutorial"). Cleaning/harmonization helpers and projections are planned.

Validation and reproducibility

The reproducibility/ folder of the GitHub repository (it is not part of the CRAN package) contains the INE inputs used in the SoftwareX article, frozen on 5 October 2026 with their provenance, INE’s published reference series, and the scripts that regenerate every reported number, table and figure offline. From a clone of the repository:

Rscript reproducibility/01_validation.R        # benchmark vs INE, sensitivity, bootstrap
Rscript reproducibility/02_manuscript_numbers.R  # every number in the article
Rscript reproducibility/03_figures.R             # the article's figures
Rscript reproducibility/04_rate_benchmark.R      # grouped death rates vs INE
Rscript reproducibility/05_fertility_benchmark.R # TFR and mean age at childbearing vs INE

Across 2002-2024, provincial e0 and e65 agree with INE’s published tables within 0.25 years for every province whose INE table closes at 95+ (see reproducibility/output/validation_summary.md in the repository), and provincial TFR and mean age at childbearing agree with INE’s published series within 0.01 in 99% and 98% of province-years, 1975-2024. Life tables are built from 2002 onwards; INE’s earlier provincial populations are top-coded at 85+.

Tests: devtools::test() runs the fixed-input suite. The full pipeline on live INE data runs when the environment variable INEDEMOGR_LIVE_TESTS=true is set (weekly in the repository’s continuous integration).
