Automobile Production, Selected Countries, 1950-2016 (in millions)

Source: International Organization of Motor Vehicle Manufacturers,
The second half of the 20th century has seen a major shift in car production. In 1950, the United States accounted for more than 80% of the global car production, which excludes commercial vehicle production. However, this share declined to about 6.5% in 2012, reflecting a loss of competitiveness of the American car manufacturing system. The United States, even if it represents the largest car market in the world, has been thoroughly motorized. This implies that the American market is mainly one of replacement with acute competition between manufacturers for market share. Roughly the same number of cars was produced in the United States during the 1990s than during the 1950s.
In the 1960s, two major players in the car industry emerged; Japan and Germany. By 1990, they respectively accounted for 27.4% and 12.7% of the global car production. However, like the United States, the market share of Japan and Germany declined to 10.5% and 8.0% of the global car production in 2016. This underlines that a growing share of car manufacturing is taking place in newly industrialized economies, but the main consumption market still remains the developed world and under the control of American, Japanese and German car manufacturers. Car manufacturing in China has experienced a spectacular growth to reach 33.9% of the global production in 2016. The financial crisis of 2008 had a substantial impact on global car production with production in the United States, Japan and Germany plummeting. However, production recovered afterwards, in part of latent demand in some advanced economies (consumers often postpone the purchase of a vehicle during a recession). Still, North America, Western Europe and Japan are replacement markets, implying that the majority of car sales are for people replacing their existing car. Since 2005, China has been the most important driver of the growth in global car production, accounting for 78% of the 26 million additional production. This is indicative of a fast motorization of the economy and rapid highway construction.

Change in Golf’s Driving Distance over Time

“The pink curve on the graph shows the mean driving distance for PGA tour professionals for every year between 1980 and 2008. The two curves either side show the average plus and minus 1 standard deviation (a measure of the variation amongst the golfers). The dots show the average driving distance for the longest driver of the year.

The graphs show a consistent increase of about 40m with much of that occurring between 1995 and 2005.”

Long Term Charts of the United States’ Energy Consumption

Dan Schroeder wanted to take a longer term look at the sources of the United States’ electricity consumption. Pulling data from the U.S. Energy Information Administration he created these beautiful charts. Check out his entire post with detailed notes here.

A Century of Coffee, Tea, and Soft Drink

Over the last hundred years consumption of coffee per capita has fallen. From a peak of 46 gallons per capita in 1946 to 19.7 gallons per capita in 2014.  The increased availability of alternatives in the 1940s, specifically carbonated soft drinks, has been attributed as one leading cause of the annual decline in coffee consumption. Using the USDA’s economic research service’s food availability data as a proxy for consumption coffee – we can see the a century’s change of coffee consumption in gallons charted against soft drinks and tea.

The last decade of decline in soft drink consumption is alarming if the data window only frames 2004-2014. But broadening our data view- the picture tells a different story.

100 Years of Technology

— In 1900, <10% of families owned a stove, or had access to electricity or phones

— In 1915, <10% of families owned a car

— In 1930, <10% of families owned a refrigerator or clothes washer

— In 1945, <10% of families owned a clothes dryer or air-conditioning

— In 1960, <10% of families owned a dishwasher or color TV

— In 1975, <10% of families owned a microwave

— In 1990, <10% of families had a cell phone or access to the Internet

Today, at least 90% of the country has a stove, electricity, car, fridge, clothes washer, air-conditioning, color TV, microwave, and cell phone.

155 Years of Crude Oil Prices

Since 1859, when George Bissell and Edwin L. Drake made the first successful use of a drilling rig at a site on Oil Creek near Titusville, Pennsylvania, oil has made its way to mainstream markets. Here’s a chart of the history of crude oil prices from 1861 to 2016.

Historical Metropolitan Populations of the United States

Random Notes and Comments

  • The urban hierarchy of the U.S. was dominated by the Northeast and Midwest until relatively recently. Between 1840 and 1900, 18 out of the top 20 metro areas were in the northeastern quadrant of the current USA, with just New Orleans, plus either Charleston or San Francisco, as the only cities in the South or West. As late as 1960, 15 out of 20 were still outside the “sunbelt”.
  • For 80 years, from 1860 to 1930 inclusive, New Orleans was the only southern city in the top 20. Before that, Charleston, SC was the dominant city of the south, falling off the list in 1850. In 1940, Houston, Dallas, and Miami began their rises, and Atlanta didn’t crack the top 20 until 1970.
  • Cincinnati was the first major city of the Midwest, making the top 20 list in 1820. By 1890 there were 9 midwestern cities in the top 20.
  • San Francisco was the only western city in the top 20 for 50 years, from 1860 to 1900 inclusive. By 1910 Los Angeles cracked the the top 20, soon overtaking its northern rival. In 2010, the West had more cities on the list (6) than any other region.
  • In 1850, 5 of the top 20 cities were in New York State: New York City (1), Albany (7), Buffalo (10), Rochester (16), and Syracuse (18). The nickname “Empire State” was very apt in the heyday of the Erie Canal.
  • Four northeastern cities (New York, Boston, Philadelphia, and Baltimore) have been in the top 20 since the first census in 1790. Washington, DC didn’t really exist in 1790, but Alexandria, VA was on the list then, and DC itself afterwards, so one could argue that the Washington metro area also has been in the top 20 since independence.
  • By 1930 Washington, DC was ranked #17, down from #5 in 1820. But the expansion of the federal government during the New Deal era and World War II propelled it up to #8 by 1970. It is the only metro area with a U-shaped curve, with a steady decline in rank followed by a steady rise.

Understanding Trends

Your hosts Gary Hoover and Dave Stanwick here hope to build the greatest compilations, discussions, and comparisons of long-term change through time ever assembled.  Trends in the largest sense, in every aspect of life.  From 3-10 years for short term looks, up to a million or more years for fundamental trends.  
We ultimately would like our friends and the world to help assemble charts, graphs, tables — visualizations of all types — followed by thought, analysis, and discussion.  
We believe our shared understanding of everything will rise: from weather to sports, from Google’s growth to the adoption of indoor plumbing, from the rise of Chicago to the fall and rise of the Boston Red Sox.  
We limit our vision to “time series” because we believe the need is great.  
Our obsession with the next quarter or next semester, our tendency to think that news matters more or is more interesting than the plate tectonics of the subject, and our affection for fads and fashions combine to blur society’s vision and thought.  We would like to help change that.
Stay tuned to watch our evolution….the journey begins…
