California's 51st Congressional District, stretching along the state's border with Mexico, is nearly 70 percent Latino, its median household income is $38,528 a year, fewer than two-thirds of its residents have high school diplomas and just 13.2 percent are college graduates.
The 18th Congressional District lies 450 miles to the northwest, encompassing the San Francisco Peninsula and much of Silicon Valley. Fewer than 17 percent of its residents are Latino, they have median household incomes of $97,001 a year, 93.6 percent have high school diplomas and 57.3 percent have college degrees.
California is a land of great cultural, demographic and economic extremes and that extends to its 53 congressional districts as well, as a new Census Bureau interactive tool demonstrates.
Data about the characteristics of every congressional district in the nation - although not political data - are instantly available on the site, making comparisons easy. About the only similarities between the 51st CD and the 18th CD is that both have virtually the same size populations, 717,000 or so, and both are represented by Democrats, first-termer Juan Vargas in the 51st and 20-year veteran Anna Eshoo in the 18th.
