2010 census
As of the 2010 United States Census, there were 62,450 people, 24,974 households, and 17,405 families living in the county. [15] The population density was 137.7 inhabitants per square mile (53.2/km2). There were 27,603 housing units at an average density of 60.9 per square mile (23.5/km2). [16] The racial makeup of the county was 95.9% white, 2.0% black or African American, 0.4% Asian, 0.2% American Indian, 0.2% from other races, and 1.4% from two or more races. Those of Hispanic or Latino origin made up 0.7% of the population. [15] In terms of ancestry, 18.0% were American, 15.4% were German, 12.9% were Irish, and 10.8% were English. [17] In Lawrence County, less than 1% of people who self-identify as "Irish" are Catholic. Scholars believe this is part of a trend in which people are vaguely aware that at least some of their ancestors come from Ireland, but that population is primarily of "Scots-Irish" or "Ulster Scots" ancestry, and those identifying as "Irish" are simply unaware of the distinction. [18] Those citing "American" ancestry in Lawrence County are of overwhelmingly English extraction, most English Americans identify simply as American because their ancestors have been in North America for centuries—in some cases since the 1600s.
