Census Records

Miller County was one of the first six counties in the Arkansas Territory, created in 1820 and containing a large part of Texas. In 1838, the county lost much of its area to Texas and was abolished. It was recreated in 1874 from part of Lafayette County. The 1820 census records for Arkansas Territory no longer exist. There are census records for 1830 but the families in 1840-1870 will be found in Lafayette County.

The 1900 Federal Census is the first census to ask for years married and asks women how many children they've borne and how many are living. It also asked for the month and year that each person was born, the year they immigrated and whether they own or rent their homes. There are also colums for street addresses but they were not generally used in rural areas.
1910 - This is the second census that asked for number of years married, number of children borne by females and number of living children.
The 1920 census was enumerated in January and many families were missed, likely due to weather. It offers very little in the way of extra information except for the names of the roads on which the people lived.
The 1930 offers addresses for folks in town, age at first marriage and veteran status.
The 1940 offers addresses for folks in town, education level, residence in 1935, employment status and total income for 1939.
