“At the beginning of 2012, the population of the United States was almost 313 million (U.S. Census Bureau, 2011), which ranks third worldwide after China and India, both of which have over 1 billion1 people. The racial and ethnic make-up is quite varied, with approximately 65% White, 16% Hispanic or Latino, 13% Black or African American and the remainder other and / or mixed racial and ethnic groups (U.S. Census Bureau, 2012). (Race and ethnicity categories are self-reported in the Census and there are no fixed criteria as to how a person identifies himself or herself.) Hispanics and Latinos are the fastest growing group, with a 49% population increase between 2000 and 2010, compared to just 5% for others (Ennis, Ríos-Vargas & Albert, 2011).
“The population figures reflect all people in the United States, both legally and undocumented. While there is not an agreed figure for the latter, some estimates put it at about 11–12 million persons (Camarota & Jensenius, 2009; Zuckerman, Waldmann & Lawton, 2011). This number increased rapidly at the beginning of the new century, growing by nearly 40% between 1999 and 2007 (Zuckerman, Waldmann & Lawton, 2011) but tapering off at the end of the decade during a major recessionary period.
“Table 1.1 provides several demographic indicators and how they have changed from 1970 to the present time. Several are typical of high-income countries. Of particular note, however, is the relatively high fertility rate. Unlike many European countries, fertility rates in the United States are at about the generally accepted “replacement rate” of 2.1 children per woman and have been relatively steady over the past 40 years. In contrast, many OECD countries have rates below 1.5 and in Japan and Korea it is around 1.2. Part of the reason is the relatively high immigration and birth rate among the Hispanic population, but even among United States Whites the birth rate is considerably higher than in most OECD countries.”
