 ## Introduction
 
-In the decades after World War II, the population of suburban areas more than doubled while the population of central cities shrank. Many of the new suburbanites were members of a growing white middle class who had grown up in cities but chose to buy their own home and raise their family in the suburbs. These affluent suburbanites may still have worked in cities, but their homes and much of their spending were in the suburbs (along with the associated property and sales tax revenue). Notably, formal and informal mechanisms–such as restrictive covenants that banned sale to people of color; zoning laws that effectively excluded poor people; and informal, discriminatory real estate broker practices–kept the suburbs nearly all white. Those who remained in the cities were disproportionately likely to be poorer people of color, often living in slums, and thus were the most in need of the social services that city governments were increasingly ill-equipped to provide.
+In one of the closest presidential elections in American history, Bush became president with only a few hundred total votes in the state of Florida, despite Gore winning the popular vote by a little over 500,000 votes nationwide. The recount efforts prompted analysts and mathematicians to consider what happens when the margins of victory are smaller than the statistical margins of error, and what role technology plays in casting and counting votes. This clip features an accessible discussion of mathematical concepts at play in such processes, as well as a debate about technological interventions like punch-card ballots, the infamous “hanging chads” in Florida recounts, and the fallibility of both humans and machines in the voting process.
 
-The clip, from a 1966 episode of *Local Issues* called “To Save a City” produced by WMVS in Milwaukee, illuminates the crucial role of the automobile and the growth of the highway system in facilitating this suburbanization; the prototypical suburban father drove into work on government-constructed freeways connecting the city and suburbs. The video clip illuminates a trend about Milwaukee that was emblematic of the country as a whole: Even while the U.S. economy thrived in the 1950s and 1960s, slum conditions prevailed in significant portions of American cities.
