Jefferson Parish (French: Paroisse de Jefferson; Spanish: Parroquia de Jefferson) is a parish in the U.S. state of Louisiana. As of the 2020 U.S. census, the population was 440,781. The parish seat is Gretna, and its largest community is Metairie. Jefferson Parish is included in the Greater New Orleans area.


1825 to 1940

Jefferson Parish was named in honor of US President Thomas Jefferson of Virginia when the parish was established by the Louisiana Legislature on February 11, 1825, a year before Jefferson died. A bronze statue of Jefferson stands at the entrance of the General Government Complex on Derbigny Street at the parish seat in Gretna. The parish seat was in the City of Lafayette, until that city was annexed by New Orleans in 1854.

Originally, this parish was larger than it is today, running from Felicity Street in New Orleans to the St. Charles Parish line. However, as New Orleans grew, it absorbed the cities of Lafayette, Jefferson City, Carrollton, and several unincorporated areas (faubourgs). These became part of Orleans Parish. The present borders between Jefferson Parish and Orleans Parish were set in 1874. The Jefferson Parish seat was moved to Gretna at the same time.

NOTE: The City of Lafayette in Jefferson Parish, as it was recorded in U.S. Census records until 1870, should not be confused with the present city of Lafayette, Louisiana, in Lafayette Parish.

1940 to 2000

From the 1940s to the 1970s, Jefferson's population swelled with an influx of middle-class white families from Orleans Parish. The parish's population doubled in size from 1940 to 1950 and again from 1950 to 1960 as the parents behind the post–World War II baby boom, profiting from rising living standards and dissatisfied with their old neighborhoods, chose relocation to new neighborhoods of detached single-family housing. By the 1960s, rising racial tensions in New Orleans complicated the impetus behind the migration, as many new arrivals sought not only more living space but also residence in a political jurisdiction independent from New Orleans proper.

The earliest postwar subdivisions were developed on the Eastbank of Jefferson Parish ("East Jefferson") along the pre-existing Jefferson Highway and Airline Highway routes, often relatively far-removed from the New Orleans city line, as land prices were lower further away from New Orleans and land assembly was easier. The completion of Veterans Highway in the late 1950s, following a route parallel to Airline but further north, stimulated more development. The arrival of I-10 in the early 1960s resulted in the demolition of some homes in the Old Metairie neighborhood, where development began in the 1920s, but resulted in even easier access to suburban East Jefferson.

In the portion of Jefferson Parish on the Westbank of the Mississippi River ("West Jefferson"), large-scale suburban development commenced with the completion, in 1958, of the Greater New Orleans Bridge crossing the Mississippi River at downtown New Orleans. Terrytown, within the city limits of Gretna, was the first large subdivision to be developed. Subsequent development has been extensive, taking place within Harvey, Marrero, Westwego and Avondale.

Similar to the development trajectory observed by other U.S. suburban areas, Jefferson began to enjoy a significant employment base by the 1970s and 1980s, shedding its earlier role as a simple bedroom community. In East Jefferson, the Causeway Boulevard corridor grew into a commercial office node, while the Elmwood neighborhood developed as a center for light manufacturing and distribution. By the mid-1990s, Jefferson Parish was exhibiting some of the symptoms presented by inner-ring suburbs throughout the United States. Median household income growth slowed, even trailing income growth rates in New Orleans proper, such that the inner city began to narrow the gap in median household income, a gap at its widest at the time of the 1980 Census. St. Tammany Parish and, to a lesser extent, St. Charles Parish began to attract migrants from New Orleans, and increasingly even from Jefferson Parish itself. These trends were catalyzed by Hurricane Katrina, which destroyed much of New Orleans' low-income housing and propelled further numbers of lower-income individuals into Jefferson Parish.

Despite these challenges, Jefferson Parish still contains the largest number of middle class residents in metropolitan New Orleans and acts as the retail hub for the entire metro area.

Hurricane Katrina (2005)

Even though Jefferson Parish was affected by Hurricane Katrina, it has rebounded more quickly than Orleans Parish, since the devastation was not as severe. The parish has a current population of 432,000, which is 15,000 fewer people than was recorded by the 2000 U.S. Census. New Orleans' Katrina-provoked population loss has resulted in Jefferson Parish becoming the second most populous parish behind East Baton Rouge Parish, center of the Baton Rouge metropolitan area.

With the landfall of Hurricane Katrina on August 29, 2005, Jefferson Parish took a hard hit. On the East Bank, widespread flooding occurred, especially in the eastern part of the parish, as well as much wind damage. Schools also were reported to have been severely damaged. On the West Bank, there was little to no flooding, though there was still much wind damage. As a result, the Jefferson Parish Council temporarily moved the parish government to Baton Rouge. Evacuees of Jefferson Parish were told that they could expect to be able to go back to their homes starting Monday, September 5, 2005 between the hours of 6 a.m. CDT and 6 p.m. CDT, but would have to return to their places of evacuation because life in the area was not sustainable. There were no open grocery stores or gas stations, and almost the entire parish had no electric, water, or sewerage services. Moreover, evacuations out of New Orleans were continuing to be staged from the heart of Metairie at the intersection of Interstate 10 and Causeway Boulevard, and traffic throughout the area was primarily restricted to emergency and utility vehicles.

Aaron Broussard, the parish president, issued the following statement, which was posted on the parish's website:

Jefferson Parish is not a safe place to return to at this time. Therefore, I am exercising my authority under the Louisiana Disaster Act and issuing a 'lock out' order for all Jefferson Parish citizens until 6 a.m. on Monday, September 5th.

I have asked the Governor to utilize the State Police and National Guard for assistance in this mandatory lockout. This time will be needed to clear debris from streets so people can enter Jefferson Parish at their own risk.

We are at a catastrophic, disastrous impasse. There are a tremendous amount of trees down, gas leaks, low water pressure, and downed electrical lines which could start a fire that we have no way of putting out. There are no traffic controls. Many places are still flooded and this standing water will become toxic.

Jefferson Parish emergency managers will need this time to at least clear major East/West thoroughfares so that you can enter Jefferson Parish. However, I strongly suggest that you just come here to gather more belongings and leave, as it will still be a dangerous place. I cannot stress strongly enough that there will be no stores to purchase food or supplies so please do so prior to coming back to Jefferson Parish.

Try to stay with friends and relatives out of the hurricane affected area during the weeks to come. We cannot sustain any viable quality of life in Jefferson Parish at this time or for some time to come.

On September 3, as thousands of New Orleans residents were being evacuated into the parish, Parish President Aaron Broussard facetiously declared on local radio that Jefferson Parish would become a separate country to be called "Jeffertania" in hopes that this would get the attention of the Federal Government. "Please excuse my cynicism," Broussard said. "I just can't take this ineffectiveness anymore."

On September 4, Jefferson Parish President Aaron Broussard broke down on Meet the Press

RUSSERT: You just heard the director of Homeland Security’s explanation of what has happened this last week. What is your reaction?

BROUSSARD: We have been abandoned by our own country. Hurricane Katrina will go down in history as one of the worst storms ever to hit an American coast. But the aftermath of Hurricane Katrina will go down as one of the worst abandonments of Americans on American soil ever in U.S. history. … Whoever is at the top of this totem pole, that totem pole needs to be chainsawed off and we’ve got to start with some new leadership. It’s not just Katrina that caused all these deaths in New Orleans here. Bureaucracy has committed murder here in the greater New Orleans area and bureaucracy has to stand trial before Congress now....

Three quick examples. We had Wal-Mart deliver three trucks of water. FEMA turned them back. They said we didn’t need them. This was a week ago. FEMA, we had 1,000 gallons of diesel fuel on a Coast Guard vessel docked in my parish. When we got there with our trucks, FEMA says don’t give you the fuel. Yesterday — yesterday — FEMA comes in and cuts all of our emergency communication lines. They cut them without notice. Our sheriff, Harry Lee, goes back in, he reconnects the line. He posts armed guards and said no one is getting near these lines…

I want to give you one last story and I’ll shut up and let you tell me whatever you want to tell me. The guy who runs this building I’m in, Emergency Management, he’s responsible for everything. His mother was trapped in St. Bernard nursing home and every day she called him and said, "Are you coming, son? Is somebody coming?" and he said, "Yeah, Mama, somebody's coming to get you." Somebody's coming to get you on Tuesday. Somebody's coming to get you on Wednesday. Somebody's coming to get you on Thursday. Somebody's coming to get you on Friday… and she drowned Friday night. She drowned Friday night! [Sobbing] Nobody's coming to get us. Nobody's coming to get us… (Video: WMV MOV)

By the following weekend, the local electrical utility, Entergy, had restored power to large swaths of Jefferson Parish, and the parish public works department had restored water and sewer service to most of the areas with power. East Jefferson General Hospital never ceased operation, even through the storm. Nevertheless, Mr. Broussard continued to discourage residents from returning until all major streets were clear of downed trees, powerlines and major debris. The parish's initial focus was on helping businesses through the "Jumpstart Jefferson" program that allowed business operators into the parish before residents. Nevertheless, some independent-minded residents began moving back into the parish even before Broussard issued a formal "all-clear", and some gas stations, grocery stores, restaurants and a Home Depot were in operation during this time.

Broussard's report of the events he discussed on Meet the Press have subsequently proven to be inaccurate. The son of the drowned woman was later identified as Thomas Rodrigue, who replied, "No, no, that's not true," when told of Broussard's account. An MSNBC interview with the man revealed that Rodrigue tried to contact his mother at the St. Rita nursing home on the days before the storm – Saturday, August 27 and Sunday, August 28, not Monday through Friday as Broussard had claimed—to encourage the home to evacuate. They did not, resulting in the deaths by drowning of more than 30 other residents.

Crucially, Jefferson's levees and floodwalls did not fail in the wake of Katrina, enabling floodwaters to be rapidly pumped out. As of October 2006, Jefferson Parish had, in effect, completely rebounded from Hurricane Katrina, while far more damaged Orleans Parish continued recovering at a slower rate. Estimates of Jefferson Parish's population ranged from 420,000 to 440,000, and this figure was expected to continue to rise as evacuated residents from Orleans Parish returned to metropolitan New Orleans.

Katrina-related flooding

Flooding on the east bank has been frequently attributed to the decision by parish leadership to deactivate the stormwater pumping systems and evacuate the operators during the storm. Katrina's substantial storm surge may have swamped even operating pumping stations but Broussard's activation of the parish's "Doomsday Plan" is the most frequently cited reason for the flooding in all areas of the east bank except Old Metairie and parts of Harahan. Pump operators were evacuated to areas outside the parish that were themselves severely affected by the storm and pump station personnel were consequently unable to immediately return to restart the pumps. They did not arrive until the morning of August 31. Water resulting from the backflow through the non-operating pumping stations, as well as storm-related rainwater, remained on the streets and in the homes of residents of Metairie and Kenner for a day and a half. Many homes which were not severely damaged by storm winds took heavy flood damage, especially along both sides of the West Esplanade canal, from the 17th Street Canal to Kenner. The parish has subsequently announced that it will change the way it evacuates critical personnel during an emergency, both through the construction of "safe-houses" and use of existing facilities on the west bank of Jefferson Parish. The original "safe-house" project was severely modified due to rising costs and was further delayed due to a conflict of interest revealed by the original contractors. There are also plans to add manual closures on the pumping stations due to the failure of the compressed air systems during Katrina's storm surge.

Much additional consideration has been given to the different problem of the flooding in Old Metairie that resulted from Jefferson Parish's reliance on the failed Orleans Parish drainage system at the 17th Street Canal and its Pumping Station No. 6. Flooding in this area south of Metairie Road between the Orleans Parish line and Causeway Boulevard was catastrophic and deep water destroyed much of the most expensive real estate in the parish. A temporary plan was devised to pool water at the Pontiff Playground and south of Airline Drive and to divert some into other Jefferson Parish drainage canals. A longer-term project to divert water from this vulnerable area into the Mississippi River has also been suggested, although its expense appears to be prohibitive. Jefferson Parish officials have also struggled to maximize the parish's ability to utilize the significantly reduced pumping capacity of the 17th Street Canal if the threat of storm surge again requires the Corps of Engineers to close the mouth of the canal.


A business report released in April 2007 found Jefferson Parish led the nation in job growth, for the quarter ending September 30, 2006,

as rebuilding continued after Hurricane Katrina. Jefferson Parish president Aaron Broussard believes that Jefferson Parish will reach pre-Katrina numbers or even exceed those numbers, as residents who are still evacuated from New Orleans return to Jefferson Parish to be closer to New Orleans as they await federal recovery money to repair their homes.

According to the U.S. Census Bureau, the parish has a total area of 665 square miles (1,720 km2), of which 296 square miles (770 km2) is land and 370 square miles (960 km2) (56%) is water.

Lake Pontchartrain is situated in the northern part of Jefferson Parish with the parish line several miles north of the southern shore, with St. Tammany Parish at its northern shore. The Mississippi River is located around the midpoint of Jefferson Parish flowing generally in a north-west to south-east direction.

Surrounding parishes include St. Tammany Parish, Louisiana at the north shore of Lake Ponchartrain, St. Charles Parish upriver to the west, Orleans Parish downriver to the east, and Plaquemines Parish downriver to the south-east. The majority of the southern half of Jefferson parish is uninhabited marshland with one of the exceptions being the town of Grand Isle; the only roads connecting Grand Isle to the rest of Jefferson Parish run through Lafourche Parish and St. Charles Parish.

In 1830, the U.S. Census Bureau reported a population of 6,846; since the 2020 U.S. census, its population has grown to 440,781 people, 171,991 households, and 108,177 families residing in the parish. In 2010, the population density was 1,410 people per square mile (574/km2) and there were 187,907 housing units at an average density of 613 per square mile (237/km2).

In 2019, the racial and ethnic makeup of the parish was an estimated 52.6% non-Hispanic white, 26.4% Black and African American, 0.3% American Indian or Alaska Native, 4.2% Asian, <0.0% Native Hawaiian or other Pacific Islander, 0.3% some other race, 1.7% two or more races, and 14.5% Hispanic or Latino American of any race. At the 2020 U.S. census, the racial and ethnic makeup was a tabulated 47.28% non-Hispanic white, 26.29% Black or African American, 0.3% American Indian or Alaska Native, 4.43% Asian, 0.02% Pacific Islander, 3.74% multiracial, and 17.94% Hispanic or Latino American of any race, representing a nationwide demographic shift of diversification from the predominant non-Hispanic white population.

Greg Rigamer, a consultant of WWL-TV Eyewitness News and demographer, stated that, between the 2000 U.S. census and the 2010 U.S. census, the overall population of Jefferson Parish decreased while its population of Hispanic and Latino Americans increased. He argued that this was due to Hispanic and Latino Americans arriving after Hurricane Katrina in 2005 to assist the already existing Hispanic and Latin community in Jefferson Parish. As of 2011, more than 15% of the parish population was Hispanic.

At the 2019 American Community Survey, there were 169,452 households and 188,511 housing units with an owner-occupied rate of 61.2%. The median value of an owner-occupied housing unit was $188,200 and median gross rent for the parish was $972. The median household income for Jefferson Parish was $54,032 and males had a median annual income of $48,933 versus $38,442 for females. Jefferson's overall poverty rate was 15.5%, and 25.3% of children under age 18 lived at or below the poverty line.

Among the religious community in Jefferson Parish, most have identified as Christian. The predominant religious institution of Christendom in the parish is the Catholic Church, primarily served by the Roman Catholic Archdiocese of New Orleans. There is also a prominent Baptist population identifying with the Southern Baptist Convention. In Gretna, there were at least two Assemblies of God USA congregations reflecting the area's Pentecostal population as of 2022. Of note among Baptists and Pentecostals, there have also been several historically Black or African American Baptist and Pentecostal churches in the parish.

The parish's public schools are operated by Jefferson Parish Public Schools. The Jefferson Parish Library operates the public libraries.

Historically a significant number of the parish's students were in private schools, and as of 2015 Catholic schools had the majority of private school students. In 2000 the parish was the American county equivalent with the second highest per capita enrollment in private school. As of October 1, 2014 there were fewer than 18,000 students in Jefferson Parish, or over 25% of the children of the ages for K-12 education, who attended private schools approved by the State of Louisiana. There were also 1,246 children in the parish who were homeschooling or who were in private schools not approved by the state.

From 2013–2014 to 2014–2015 the percentage of students in the parish's private schools declined by 4%; the Catholic schools specifically had the same percentage of enrollment decline. The non-Catholic private schools together had a 3% decline. Jessica Williams of The Times Picayune stated that the establishment of charter schools and improved options in Jefferson Parish district schools, along with Hurricane Katrina in 2005 and the 2008 recession, caused decreases in private school enrollment.
