Federal censuses were taken every 10 years. Louisiana became a state in 1803. So, the first federal census records for the state were taken in 1810. Many of those records are widely available and published.
However, researchers should note that both Spanish and French people listed in federal census records may have had their names misspelled, or their names may not have been properly transcribed when copies were being made. Certain pieces of information may also be omitted completely.
The federal government started to list Native Americans in various records starting in the 1860s. There were special Indian schedules created in 1900 and 1910. While similar to other population schedules of the time, they included a second page.
That page listed the tribes of the individual and their parents, as well as the racial mixture, if not fully Native American. Researchers can find those schedules in the district or ward that was home to the Native American of interest.
Duke University in Durham, North Carolina holds some federal census supplements for the state of Louisiana. The National Archives has microfilmed copies of the mortality schedules for Louisiana from 1850 to 1880 on file.
Control of Louisiana was taken from the French by the Spanish during the colonial period. The United States did not gain possession of it until 1803. The Spanish and the French took census records up to that point, while the first United States federal census of the area was not taken until 1810. Many of the Spanish records have been translated to English and published.
The Spanish city of Nuestra Se?ora del Pilar de los Adaes was the capital of Texas from 1721 to 1773. It was located near what is now Robeline, Louisiana, at what is now Natchitoches Parish. In 1773, the city was abandoned and those who left it went to San Antonio, instead.
However, the mission at Nacogdoches, Texas was reestablished in 1779, when many settlers moved back to the Adaes area from San Antonio. The census reports for that mission for each year from 1792 to 1806 are extant, along with the report from 1909.
