The New Orleans metropolitan area, designated the New Orleans–Metairie metropolitan statistical area by the U.S. Office of Management and Budget,^[3] or simply Greater New Orleans (French: Grande Nouvelle-Orléans, Spanish: Gran Nueva Orleans), is a metropolitan statistical area designated by the United States Census Bureau encompassing seven Louisiana parishes—the equivalent of counties in other U.S. states—centered on the city of New Orleans. The population of Greater New Orleans was 1,271,845 in 2020,^[4] up from 1,189,166 at the 2010 United States census. Greater New Orleans is the most populous metropolitan area in Louisiana, and the 45th most populous in the United States. According to 2017 census estimates, the broader New Orleans–Metairie–Slidell combined statistical area (CSA) had a population of 1,510,562.

The New Orleans metropolitan area was devastated by Hurricane Katrina—once a category 5 hurricane, but a category 3 storm at landfall—on August 29, 2005.^[5] Within the city of New Orleans proper, multiple breaches and structural failures occurred in the system of levees and flood walls designed under federal government auspices. The city of New Orleans experienced a steep population decline after the hurricane, though by the 2020 census, it had regained a good portion of that loss.

The post-August 2005 decline in the city's population negatively impacted population numbers for the entire metropolitan area, which had a population of 1,337,726 million as recorded in the 2000 United States census. Most of the decline in population was accounted for by the decline experienced in the city of New Orleans proper (coterminous with Orleans Parish); the U.S. Census Bureau estimates that the city's population dropped from 453,728 prior to the storm (July 1, 2005) to 389,476, the estimate for 2020.^[6][7]

Greater New Orleans is the largest regional economy in Louisiana and borders the second largest economically-important area, Greater Baton Rouge.^[8] One Fortune 500 company is headquartered in the region, Entergy.^[9] The largest companies operating in the New Orleans metropolitan area are Globalstar, AT&T, GE Capital, and the Port of New Orleans. Home to some of Louisiana's most-visited tourist destinations, tourists have spent over $10.05 billion in 2019.^[10]

For U.S. census purposes, the New Orleans–Metairie metropolitan statistical area includes seven parishes: Jefferson, Orleans (coterminous with the city of New Orleans), Plaquemines, St. Bernard, St. Charles, St. James, and St. John the Baptist.^[11]

St. Tammany, Tangipahoa, and Washington parishes all lie across Lake Ponchartrain from New Orleans, and are oftentimes included as part of the region.

According to the New Orleans region's chamber of commerce, GNO, Inc.^[12] (formerly Metrovision), the region boasts a civilian labor force of over 650,000 and there are over 65,000 students enrolled in the region's nine universities and eight community/technical colleges.^[13]

The Louisiana State Legislature created a commission (the Regional Planning Commission) to be responsible for the planning and development of the New Orleans metropolitan area. The eight parishes covered by the commission are: Jefferson, Orleans, Plaquemines, St. Bernard, St. Charles, St. John the Baptist, St. Tammany and Tangipahoa.

Each parish within the New Orleans metropolitan area and New Orleans–Metairie–Slidell combined statistical areas lie on a very low sea level elevation, though further inland near the Mississippi border its area above sea level increases to 371 feet.

The New Orleans metropolitan area was first defined in 1950. Then known as the New Orleans standard metropolitan area (New Orleans SMA), it consisted of three parishes—Orleans, Jefferson, and St. Bernard—and had a population of 685,405.^[15][16] Following a term change by the Bureau of the Budget (present-day U.S. Office of Management and Budget), the New Orleans SMA was called the New Orleans standard metropolitan statistical area (New Orleans SMSA).^[17] By the census of 1960, the population had grown to 868,480, a 27% increase over the previous census.^[16]

St. Tammany Parish was added to the New Orleans SMSA in 1963.^[18] The four-parish area had a combined population of 899,123 in 1960 and 1,045,809 in 1970.^[16] By the 1980 census, the population had increased by 14% to 1,187,073.^[16]

In 1983, the official name was changed to the New Orleans metropolitan statistical area (New Orleans MSA).^[17] Two more parishes, St. Charles and St. John the Baptist, were added to the metropolitan area the same year, making a six-parish MSA.^[19] The newly defined area had a total of 1,256,256 residents in 1980, but that number had declined to 1,238,816 in 1990.^[16]

The New Orleans MSA expanded to eight parishes in 1993 with the inclusion of Plaquemines and St. James.^[20] The eight-parish area had a combined population of 1,285,270 at the 1990 census and 1,337,726 in 2000.

The MSA was renamed the New Orleans–Metairie–Kenner metropolitan statistical area in 2003, and St. James Parish was removed. At the 2010 U.S. census, the metropolitan statistical area's population grew to 1,189,166. The overall racial composition of the New Orleans metropolitan area was as follows:^[21] White 58.2% (non-Hispanic white 52.4%), Black or African American 32.5%, American Indian 0.8%, Asian 3.5%, some other race 2.8%, two or more races 2.0%, and Hispanic or Latino (of any race) 8.6%. For those under 18, the majority are minority, with only 45.2% being non-Hispanic whites.

In 2013, St. James was once again included in the MSA, which at the same time was renamed to "New Orleans–Metairie".^[22][23] The 2019 U.S. census estimates determined the New Orleans metropolitan area's population stood at 1,270,530.^[24] In 2020, its population increased to 1,271,845.^[4] Of the metropolitan population, 485,267 households made up the area with an average of 2.6 persons per household. An estimated 50% of households were married couples, 7% had a male householder with no female present, 23% female with no male householder present, and 19% non-family households. Roughly 43% of the metropolitan population was married and 57% were unmarried. The Greater New Orleans unmarried population included 40% males and 36% females never married.

In 2019, there were 561,747 housing units and 63% were owner-occupied.^[24] Nearly 70% of the households were single unit households, 28% were multi-units and approximately 3% were mobile homes. The median value of owner-occupied housing units was $211,900, about 25% higher than the amount in Louisiana at the time ($172,100). At the 2019 estimates 47% of housing units were from under $100,000 to $100,000 to $200,000. The New Orleans metropolitan area gained 12.5% of move-ins since 2018.^[24]

Almost 8% of the population were foreign-born with the majority of origins from Latin America and Asia. The predominant language spoken among the racial and ethnic makeup is English only, followed by Spanish. Greater New Orleans residents had an estimated per capita income of $31,889 and median household income of $55,710. Roughly 16.4% of the metropolis lived at or below the poverty line.

In 2023, St. Tammany was split off into its own metropolitan area,^[25] leaving the New Orleans MSA with seven parishes and tabulating an adjusted 2020 census population of 1,007,275.

The New Orleans–Metairie–Slidell combined statistical area (CSA) is made up of nine Louisiana parishes and one Mississippi county. The CSA includes two metropolitan areas and two micropolitan areas.

In 2022 following a redrawing of the former New Orleans–Metairie–Hammond combined statistical area, and the addition of a Slidell metropolitan area, it had a census-estimated population of 1,485,510.^[26]

In 2019, the racial and ethnic makeup of the combined statistical area was 54% White, 33% Black or African American, 3% Asian, 2% from two or more races, and 8% Hispanic or Latino of any race.
