This indicator measures the economic progress of the most vulnerable segment of society, specifically the bottom 40% of the population, by calculating the annualized average growth rate of their per capita real consumption or income over a period of approximately five years. Utilizing data from household surveys and adjusting for Purchasing Power Parity (PPP) as of 2017, it provides a clearer picture of economic disparities within a nation. The calculation involves comparing mean figures from the earliest and latest surveys, allowing for insights into trends in wealth distribution and poverty alleviation efforts. It's crucial to note that data collection challenges may obscure the accuracy in regions affected by socio-economic instability, highlighting the importance of continued focus on equitable growth policies.
