The primary health care (PHC) system is acclaimed globally to be key in achieving universal health targets; however, its performance over the years has fallen short of this expectation, particularly in developing countries, including Nigeria. This paper reports the findings of the study on the availability, accessibility, and utilization of PHC services in Ogun and Oyo states. The study employed qualitative and survey research methods. The study location was in Ogun and Oyo states in Nigeria. Descriptive analysis of data was carried out. The findings show that 84% of the population had a government PHC facility in their own community, accessible to 54.5%, and utilized by 53.7% of the population. This paper recommends that the existing PHCs should be rehabilitated and equipped with modern equipment. More health experts should be employed in PHCs. Communities should be encouraged to utilize PHCs in their neighborhoods.
