The escalation of population growth has emerged as a significant concern globally, particularly in regions experiencing rapid urbanization and sustained high birth rates, such as many developing countries. This study is aimed at examining the impact of population growth in Port Harcourt metropolis from 2000 – 2023. Purposive sampling techniques were used in the investigation. A sample of 348 respondents was drawn from the population. Primary data served as the study's main source of data. The data generated were analysed using tables, frequency counts, simple percentages, descriptive statistics, mean and standard deviation in attaining data. The study sheds light on the multifaceted factors driving population growth, including economic opportunities, healthcare services, housing options, and demographic shifts. These factors collectively shape migration patterns, residential dynamics, and the overall urban landscape. The study reveals that economic opportunities and job prospects emerged as significant drivers of population growth, with a mean score of 2.72 and a standard deviation of 0.46. The study concluded that economic causes and migratory patterns have played a major role in the Port Harcourt Metropolis' population increase, which has made urban congestion and infrastructural issues worse.
