Infrastructure in America
I'm working on a post about public investment in infrastructure for Bloomberg, and I came across some interesting data from the U.S. Census Bureau that clarifies what, more exactly, we're spending money on when we're spending on "infrastructure."
One striking thing to note in this data is the dominance of highway and street construction and maintenance over all other forms of transportation infrastructure. For every dollar federal, state, and local governments spend on roadwork, only a quarter goes to alternative transportation investments. There's a lot packed into the remaining 9 percent: railways, canals, seaports, airports, and so on.
The fractions have stayed roughly constant since 2002. See here for the original time series data on FRED.
