The human population has been growing for thousands of years, and as of 2013 there are over seven billion people on Earth. This study aims to determine the yearly population trends of the world, project the population growth in the next 50 years, and identify the factors affecting the population growth. Studies on population in the past are innermost but this study focuses on the trending of the world population in the next 50 years from date. The drift of the population growth of the world may weaken or strengthen economic concerns of the national or global development; in the same manner population of a country may imply economic and social changes. This paper uses time series analysis. The study concludes that the world population increases every year and in the next 50 years the total population of the world continually gets bigger and bigger. It is approximately 79283607 annual increases and in the next half century, the world population gets bigger.There is a definite growth that shows that the world’s population has bloated and this result of the increase in population lead crises and problems such as overcrowding, poverty, crime, and rise in unemployment. The fertility and mortality affect the rise and fall of the population, but it was found out that there are more babies born everyday rather than mortality.
