2020 Bangladesh Population Overview
Bangladesh had about 169 million people in 2020 and ranks as the eighth largest country by population worldwide. With land area at 147,570km², population density reached 1,145 persons/km², the highest among large countries outside city-states. Population growth slowed to 1.0%, down from the 2.5% level in the 1980s, yet absolute population continues to rise by roughly 1.7 million people per year.
The defining characteristic is a strong demographic dividend. The working-age population (15–64) is 66.5% (112 million people), supported by a low dependency ratio. This phase is expected to continue until 2040. Median age is 27.9, far younger than Korea (43.7) and Japan (48.4), forming the basis for consumer-market expansion and abundant labor supply.
Age Structure and Demographic Dividend
Bangladesh’s age pyramid is in transition from an expansive profile toward a more stable shape. Children aged 0–14 account for 26.1%, down 10 percentage points from 36.5% in 2000. Seniors aged 65 and over remain relatively low at 5.4%. The core signal is the working-age share of 66.5%, which has reached a historical peak, amplifying the demographic dividend period. The total dependency ratio is 50.4%, meaning two workers support one non-working person. This resembles Korea’s demographic structure in the 1990s, suggesting favorable conditions for rapid industrialization.

Urbanization and Labor Characteristics
Bangladesh’s urbanization rate of 38.2% is slightly above the South Asian average of 35% and rising by 3.5% per year. Dhaka Metropolitan, with about 22 million residents, ranks among the world's largest megacities and generates around 35% of national GDP. The main driver is rural-to-urban migration linked to garment jobs, with roughly 500,000 people moving to Dhaka annually. On the workforce side, informal employment exceeds 85% among 71 million participants, meaning social protection and labor standards remain weak despite broad participation. Female labor participation at 36.3% is high for the region; RMG employs about 4 million women, and this segment is central to Bangladesh’s industrial workforce. A youth unemployment rate of 11.9% points to education–job mismatch and strengthens the policy need for vocational training.
Market Scale and Implications for Korean Firms
Bangladesh's 169 million people provide Korean firms with both a large consumer market and abundant labor. The very young age structure and the ongoing demographic dividend through around 2040 satisfy key preconditions for demographic-driven catch-up growth. A middle class of 30 million (rising to 50 million by 2030) is already the core demand base for Korean consumer goods, electronics, and digital products. A workforce of 112 million creates scope for manufacturing expansion, while overcrowding, education gaps, and climate risks represent both constraints and opportunities. Strategic utilization of the demographic dividend window is central to any long-term market strategy.
