Goa has the lowest population density among the states in India.

Population Density in Goa:
- Goa is a state located on the western coast of India with a population density of approximately 394 people per square kilometer.
- Despite being the smallest state in terms of area, Goa has a relatively low population density compared to other states in India.

Reasons for Low Population Density in Goa:
- Tourism: Goa is a popular tourist destination known for its beaches, nightlife, and heritage sites. The influx of tourists contributes to the state's economy but does not significantly impact the resident population.
- Limited land area: Goa has a small geographical area compared to other states, which limits the scope for large-scale population growth.
- Migration: Many Goans migrate to other states or countries for better job opportunities, resulting in a lower population density within the state.

Impact of Low Population Density:
- Better quality of life: With a lower population density, Goa can provide better infrastructure, healthcare, and education facilities to its residents.
- Environmental preservation: The low population density helps in preserving the natural beauty and ecological balance of the state.
- Sustainable development: The state can focus on sustainable development practices due to its lower population density.

In conclusion, Goa's low population density can be attributed to its tourism-driven economy, limited land area, and migration trends. Despite its small size, the state benefits from a better quality of life, environmental preservation, and sustainable development initiatives.
