Estimates of the Hispanic population have traditionally been based on historical trends, ratios, or some variant of the cohort-component method. In this article, we describe and test a methodology in which estimates of the Hispanic population are based on symptomatic indicators of population change such as births, deaths, and school enrollments. Methods. Using a variety of techniques, we develop Hispanic population estimates for counties in Florida. We evaluate the accuracy of those estimates by comparing them with 2000 census counts.
Paper presented at the annual meeting of the Southern Demographic Association, Hilton Head, South Carolina This paper evaluates summary measures of population projection accuracy and bias for a large sample of counties and county equivalents in the continental United States over the period 1900–2000. The analysis has two primary purposes. The first is to investigate the relationship between accuracy and bias and the length of the projection horizon and base period.
A chain of supermarkets decides to launch a new line of ethnic foods. Where should it concentrate its marketing efforts? A school district is plagued by increasingly crowded elementary schools. Is this a temporary phenomenon or a continuing long-run trend? A hospital considers adding an obstetrics unit. Will anticipated service demand cover the additional costs?

In this study, we describe an approach that can be used to estimate the demographic impact of hurricanes and other natural disasters, provide a detailed assessment of the 2004 hurricane season in Florida, compare the 2004 hurricanes with Hurricanes Andrew (1992) and Katrina (2005), and draw several conclusions regarding the likely impact of hurricanes and other natural disasters on future population growth.
