Chapter 2 Introduction

The first edition of the IGI consisted of three pillars, namely economy, living conditions and equality (Barnat et al., n.d.) and was composed of 21 indicators, including one environmental indicator (carbon dioxide - CO$_2$ emissions under pillar 2). This new, expanded IGI includes more equality metrics addressing gender inequality more broadly, and includes a new separate pillar dedicated to environmental issues. These were highlighted as potential development areas of the original index, and can now be addressed also due to progress with data availability for countries.

The current edition of the IGI is comprised of four pillars and 27 indicators. Indicators were selected as for the SDG Pulse 2022, however updated for new available data series such as when constant prices were rebased (GDP, poverty etc.).

Overview:

Number of countries: 129 economies
Number of pillars: 4 pillars
Number of indicators: 27 indicators
Years coverage:
- Data collected, imputed and forecasted for the period 2000-2023
- Index compiled only for one year - 2021

Pillars:

Pillar 1 – Economic growth
Pillar 2 - Living conditions
Pillar 3 – Equality
Pillar 4 - Environment

2.1 Data description

All data information is stored as an R object. These results are still preliminary, the final structure has to be finalized when the results are obtained.

IGI <- readRDS("IGI.rds")
class(IGI)

## [1] "IGI"

The IGI object returned as an output is a list containing the following elements:

IGI: the scores for each component or category and the IGI values for all countries and all years
intermediate_data: a list containing the data at the various steps of the data pipeline
paths: a list containing the paths set by the user
controls: a list of various controls set by the user
indicators_metadata: a tibble of the input file indicators_metadata.csv
countries_metadata: a tibble of the input file countries_metadata.csv
countries_names: a vector of the names of the countries that are considered
indicators_initial: a vector of names of the initial indicators
indicators_initial_main: a vector of names of the main initial indicators
indicators_initial_auxiliary: a vector of names of the auxiliary initial indicators
indicators_initial_categories: a named list with names corresponding to the various categories of the initial indicators and whose elements are vectors of the names of the indicators for these categories.
indicators_final: a vector of names of the final indicators (those used in the PCA)
indicators_categories: a named list with names corresponding to the various categories of the final indicators and whose elements are vectors of the names of the indicators for these categories.
NA_diagnostics: a list of 2 summary tibbles containing the proportion of missing data (one where the result is summarized by country, and the other where the result is summarized by years)
Miss: a tibble with boolean values for the indicators (TRUE: data is missing, FALSE: data is not missing)
