Bangladesh has a population of over 148 million, making it the 8th most populous country. It has the highest population density in the world at over 1,000 people per square kilometer. The three major sectors that drive Bangladesh's economy are population, education, and healthcare. The population is predominantly Muslim and urbanization has been increasing over time. Literacy rates and access to education have also been improving through government programs that provide free food to students. However, healthcare spending and access remain challenges due to the large population and communicable diseases. Reforms aim to increase healthcare funding and coverage through public-private partnerships.
