Louisiana’s population is estimated at around 4.6 million people, but the state has been experiencing a steady population decline in recent years.
Many residents have moved to other states for job opportunities, lower living costs, or improved quality of life. However, even as the state’s population decreases overall, several major cities remain important population centers, with some areas even seeing modest growth.
Louisiana Population Trends Show Decline Across the State
Population trends show that Louisiana is among the states experiencing the most consistent population loss in the United States.
Experts say several factors contribute to this decline, including:
- Economic opportunities in other states
- Natural disasters and climate concerns
- Cost-of-living challenges
- Crime and quality-of-life issues in some urban areas
Despite these challenges, some Louisiana cities still maintain strong populations or modest growth due to local economies, universities, and cultural attractions.
Below are the six most populated cities in Louisiana, according to WorldAtlas and recent census data.
1. New Orleans
New Orleans is the most populated city in the state, with about 390,128 residents within city limits.
The city is unique because it functions as a consolidated city-parish, meaning the city and Orleans Parish share the same boundaries.
While New Orleans continues to attract residents with its tourism, culture, and business opportunities, recent data shows the city is experiencing noticeable population decline.
2. Baton Rouge
Baton Rouge ranks as the second-largest city in the state with a population of 216,701.
Baton Rouge serves as Louisiana’s state capital and is the parish seat of East Baton Rouge Parish.
The city is also home to Louisiana State University and several large industrial operations.
While the Baton Rouge metropolitan area is growing, the city itself has seen a slight population decline.
3. Shreveport
Shreveport is the third-largest city in Louisiana with approximately 183,819 residents.
Founded in 1836, the city once thrived as a hub for the oil industry.
However, economic shifts and industry changes contributed to long-term population decline. Reports suggest the city continues to experience steady population loss.
4. Metairie
Metairie, located in Jefferson Parish, has a population of about 143,481 residents.
Metairie is part of the greater New Orleans metropolitan area and is known for its suburban lifestyle combined with easy access to the city.
Population trends in Metairie show slight growth or overall stagnation, depending on the data source.
5. Lafayette
Lafayette has a population of around 124,561 and serves as the parish seat of Lafayette Parish.
The city is home to the University of Louisiana at Lafayette.
Unlike many other Louisiana cities, Lafayette and its surrounding metro area have seen steady population growth, partly due to its cultural appeal and relatively affordable cost of living.
6. Lake Charles
Lake Charles has a population of approximately 80,169 and serves as the parish seat of Calcasieu Parish.
The region has recently been labeled one of Louisiana’s biggest boomtowns due to strong job growth in the broader metropolitan area.
However, despite economic growth in the region, the population within the city itself has slightly declined.
