Explanation:
The Millennium Development Goals (MDGs) were established by the United Nations in 2000 with the primary objective of halving the 1990 rate of extreme poverty by the year 2015. Target 1A specifically aimed to reduce the proportion of the global population living on less than $1.25 a day within this twenty-five-year timeframe. This goal was successfully achieved five years ahead of schedule, in 2010, leading to the subsequent adoption of the Sustainable Development Goals (SDGs) to continue global development efforts through 2030.
