The coming boom in Utah's school age and college age populations: state and county scenarios | 2002-09 | Population analysts have for some time anticipated a significant increase in the school age population (5 through 17 years of age) of Utah beginning around 2004 and extending for at least a decade. At this point the question is not whether the boom will materialize, but rather, the exact timing, mag... | |

Revised Utah population estimates for the 1990s | 2001-05 | Every 10 years, the U.S. Bureau of the Census conducts a population count. In the intervening years the Utah Population Es timates Committee (UPEC) annually prepares total resident population estimates for each of the 29 counties in the state. These estimates are based on methods that ut i l i z e s... | |

Immigrants transform Utah: entering a new era of diversity | 2004-05 | Utah is generally perceived as an extremely homogeneous state whose population can trace its ancestry mostly to northern Europe. Listings for surnames like Hansen, Jensen, and Christensen do fill many pages in local telephone directories throughout the state. According to census counts, the minority... | |

Fast-tracking Wasatch Front transit investments: economic and demographic impacts of a 2025 build-out | 2011 | Over the next 30 years, the Wasatch Front will significantly expand its transit network. Plans include the construction of an additional 25 miles of light rail, 76 miles of commuter rail, 227 miles of bus rapid transit, and 29 miles of mountain transportation rail line. These projects will be built ... | |

Demographic trends affecting public education in Utah | 2000-11 | Beginning in 2004 and continuing for at least a decade, the school age population (5 to 18 year olds) in Utah will increase significantly. Throughout the 1990s, the school age population in Utah grew more slowly than did the population in general so that its share in the total population declined. T... | |

Utah's place in the macro-demographics of the U.S. in the 20th century | 2006-03 | Utah has evolved from an isolated rural state of fewer than 300,000 in 1900 to a mostly urban state of 2.5 million today. This paper is an attempt to place this population growth within the context of the broadest outlines of national population dynamics over the past century. The growth and regiona... | |

Utah's demographic transformation: a view into the future | 2008 | Utah, along with the rest of the nation, is in the midst of an extraordinary demographic transformation which has far from run its course. The confluence of four major trends continues to dramatically reshape the size and composition of the national and state populations. These trends include the ar... | |
