Oklahoma ranks 28th in population among other U.S. states with approximately 3.9 million people as estimated by the U.S. Census Bureau for 2018. Around 78% population qualifies as urban based on the Census, but only 2% of the land mass is urban, indicating that the state itself is primarily rural. Nearly 75% of the population is Caucasian but only 8% African-American. However, of the people living with HIV (PLWH), African-Americans make up about 25% of the total, while Caucasians comprise 56%. This illustrates again the disproportionate impact of HIV on minority populations seen across the country.
