World Development Indicators Analysis (2022)

1 Introduction

This report analyses selected indicators from the World Development Indicators (WDI) dataset for the year 2022 (worldbank2022?).

The objective is to explore relationships between economic and social development variables across countries, particularly the link between income levels and human development outcomes (todaro2015?).

As shown in Figure 1, there is a clear positive relationship between GDP per capita and life expectancy across countries.

The summary statistics reveal substantial inequality in income levels across countries. GDP per capita ranges from very low-income economies to extremely high-income economies, with a large standard deviation indicating strong dispersion. Life expectancy shows less variation than income, suggesting that improvements in income are associated with diminishing health gains at higher levels of development. Unemployment rates vary considerably, reflecting differences in labour market structures and economic stability across countries.
