The demand for health literacy in family planning continues to be a global issue, particularly in developing regions. It is also estimated that over 225 million women in developing countries face challenges accessing and utilizing family planning services. Sub-Saharan Africa has the lowest family planning prevalence, at 24%, with high unmet needs, despite global efforts to improve access and knowledge. This study aimed at assessing the family planning services among pregnant women in Arumeru District, Tanzania. Using a sample size of 269 respondents, data was collected through questionnaires and interviews with healthcare officers between February and March 2024. Data were then analyzed using descriptive statistics techniques for quantitative data whereas qualitative data were analyzed using content analysis approach. Results reveal that 92.9% of respondents were aware of family planning services, with varying levels of understanding. Education and occupation played significant roles in awareness, with younger, educated individuals showing higher knowledge. Improving awareness about maternal and child health can lead to better healthcare practices, timely interventions, and increased utilization of services, ultimately reducing mortality rates and contributing to broader public health goals of improved health equity and universal health coverage. However, cultural, religious, and literacy barriers continue to hinder full understanding. The study concludes that respondents in the study area have high level of awareness regarding family planning, particularly among younger individuals and those with higher education levels. The study recommends targeted awareness programs, especially for underserved populations, and emphasizes the importance of involving men in family planning education to improve reproductive health outcomes.
