The flow of goods between states

This map shows the flow of all domestic freight between states in 2015 using data from the Freight Analysis Framework, which is a comprehensive accounting of all commercial freight movement between states by all modes of transportation. This includes freight moved by trucks, trains, planes and pipelines, but excludes foreign imports and exports and freights transported within a state.

How to read it: The arrows represent the origin and destination of goods shipped between states. Thicker and darker arrows indicate higher volume (each commodity is scaled relative to the highest volume between any two states, so arrow size isn't comparable across commodities).

Note: The Standard Classification descriptions can be deceptively narrow but often cover large groups of goods. Complete documentation is available here; Data: Center for Transportation Analysis; Graphic: Chris Canipe / Axios

Some relationships are head-scratchers at first glance. For instance, the Alcoholic beverages category shows an outsize role for Iowa, which is not necessarily known for its beer and wine industry. But the full category description covers "denatured" alcohol, which includes corn-based ethanol.

Some anomalies may be explained by steps within a supply chain. A manufacturer in California may ship to a wholesaler in Missouri, who then ships to a retailer in Texas. Some raw materials go through a distillery or rendering process before shipping elsewhere for sale or consumption. But then why is so much building stone shipped from Texas to Alabama?

Do you have an explanation for other state-to-state routes that look out of place? Send me an email at canipe@axios.com. I'd love to hear from you.

What else we saw:

  • Nearly 16 million kilotons of domestic goods shipped within the United States in 2015.
  • Fossil fuels are by far the most-shipped commodity within the United States. Coal, gasoline, fuel oils and natural gas represent one-third of all freight traffic in 2015.
  • Twenty-eight percent of all plastics and rubber transported in America flow out of Texas
  • The vast majority of coal in the U.S. is produced in Wyoming — not Appalachia — and shipped within the Midwest.
  • Most metallic ore comes from Minnesota, which is the highest producer of iron ore.
  • Thirty-nine percent of all pharmaceuticals shipped originated from California, Texas, New Jersey and Pennsylvania. New Jersey to California represents the highest-volume state-to-state route.

States will be the battlegrounds for 2020 tech policy fights

The tech industry's most consequential policy fights in 2020 will play out in the states, not Washington.

Why it matters: Momentum on a range of tech issues, from governing online privacy to regulating the gig economy, has stalled in D.C. as impeachment and election campaigns consume attention. State leaders and legislators are stepping in to fill the void.

Census data projects shift in states' congressional power

California is projected to lose a congressional seat for the first time next year, while states President Trump won such as Texas and Florida will likely gain seats, according to an analysis of new Census data by the Brookings Institution's William Frey.

Why it matters: It only takes a handful of seats to shift a party's power in Congress for a decade. The new data underscores the need for an accurate 2020 Census count, especially with changing demographics in states with booming populations such as Florida, Texas and Arizona.

California's youth population dropped by more than 400,000 throughout the past 10 years to 8.9 million young people, attributed, in part, to a drop in immigrant inflows and the state’s lowest birth rate in history, Bloomberg reports, citing the latest Census data.

The big picture: The youth slump is a trend across the U.S., where 30 states noted a dip in the under-18 age group between 2010 and 2019, newly released data shows.
