National Economic and Demographic Development

This dataset provides a comprehensive, structured relational view of global economic performance and demographic transitions over a 54-year period (1970–2024). The data is organized into five normalized tables designed for relational database research and analysis. The core of the dataset is the COUNTRY entity, which serves as a dimensional hub for three major indicator groups: Economic Indicators, Demographic Statistics, and Investment Infrastructure.

Economic indicators include Gross Domestic Product (GDP) in current USD, GDP per Capita, Inflation rates (CPI), and Unemployment rates. Demographic statistics track Total Population, Life Expectancy at birth, Median Age, and Rural/Urban population shifts. Finally, the Investment Infrastructure table captures public spending on education and healthcare as a percentage of GDP, along with Gross Fixed Capital Formation (Infrastructure Investment) in USD.

The primary objective of this dataset is to enable researchers to analyze the multi-dimensional correlations between financial growth and human development. For example, users can query the relationship between healthcare spending (Investment) and life expectancy (Demographics) or observe how rapid urbanization impacts regional inflation rates. By providing the data in a normalized format, this collection eliminates the redundancy typically found in flat-file World Bank exports, making it ready for immediate import into SQL-based environments for complex join-based analysis and longitudinal studies.
