The 2010 United States Census reported that Boulevard had a population of 315. However, other sources report a population of more than 2000. The discrepancy is likely due to exactly which areas are included in the unincorporated area. The population density was 80.7 people per square mile (31.2/km). The racial makeup of Boulevard was 272 (86.3%) White, 2 (0.6%) African American, 7 (2.2%) Native American, 3 (1.0%) Asian, 0 (0.0%) Pacific Islander, 14 (4.4%) from other races, and 17 (5.4%) from two or more races.
