This study can be done by looking into the most recent statistics. This type of information can tell you approximately how many people are living in the area, the age ranges, the sex, the race, and the rate of birth and death. Another trend would be fertility trends, which will allow you to compare that information to population trends. The most average age in 2003 to have a child was 25-29 (Torrens & Williams, 2008, pp 48). By comparing this data, if would make sense that if you have a large amount of this age range, you could assume, that the fertility rate is fairly high. You would need to see if you could locate studies that further went into fertility issues that may have a negative impact on this
