The region’s population has experienced significant changes during the last 50 years. Population increased dramatically during the 1960s and 1970s, primarily due to the growth of the oil and gas industry. Then, in the early 1980s the region encountered a significant decline in population, attributed to the oil bust. Prior to Hurricanes Katrina and Rita, in 2005, the region maintained a population of approximately 1.3 million. Katrina and Rita amplified pre-existing shifts in population: Orleans, Plaquemines and St. Bernard parishes endured dramatic population losses, whereas St. Charles, St. John, St. Tammany and Tangipahoa parishes gained residents. The current population of the region is approximately 1.3 million.
