This paper analyzes the fertility rate or the number of live births per 1,000 women aged 15-44 years old. The research is based off of census data from the Statistical Abstract of the United States from 1990 to 2009. The purpose of researching fertility and birth rates is to explain the slight fluctuations during this time frame. This study looks into the factors as to why this change has occurred, such as race, education, marital status, economic impact, age, and region. The results from over the past 20 years have proven that these demographic and geographic factors have both affected the variations of the fertility rates across the U.S.
