Automobiles: The affordable ($525-$700) Ford Model “T”, first produced in 1910, was the top selling car in the United States in 1913. The engine was started with a hand crank, and ran at a top speed of 45 m.p.h., although most city was driving was done at 25 m.p.h. or below. More here.
Demographics: The U.S. immigrant population reach an all-time high in 1910, at 14.7 percent of the whole. Italians, Poles, and other slavs were the immigrant population groups that peaked in the early 20th century.
The average household size was 4.5 people in 1910 (2.5 in 2000).
In 1913, women could vote in the states of Wyoming, Colorado, Utah, Idaho, Washington, California, Oregon, and Kansas. Illinois granted women a new form of partial suffrage in 1913 by allowing them to vote only in presidential elections, the next being in 1916.
Education: In 1910, 23.8% of the population had less than 5 years of elementary school, while only 13.5% had high school completion or higher; only 2.7% had four or more years of college.
Economy: The 16th Amendment was ratified in 1913 to legalize the income tax, which had been effectively prohibited by the Supreme Court in the 1895. The first income taxes were primarily on the wealthy.
The average hourly wage in manufacturing jobs was 21¢ in 1913.
Sports: Baseball was the only major professional sport. All games were played in the daytime. Football and basketball were played mostly by college teams.
Motion pictures: Movies were still considered a low art for the masses. Feature-length motion pictures had just been introduced in America in 1912, and by September 1913 only 12 had been produced there. Most movie programs were still made up of several short subjects, often alternating with live vaudeville acts and sing-along slides. The programs changed weekly, and so people usually went to the movies weekly. Popular stars included “Broncho Billy” Anderson and Mary Pickford, although the “star system” was still in its infancy. The first cliffhanger serial, The Adventures of Kathlyn, was released in 1913.
Telephones: Fewer than 1 in 4 households had a telephone in 1913. Virtually all calls were handled by operators. Long distance calls were prohibitively expensive; transcontinental calls were not possible. The telegraph was the preferred method of fast messaging over long distances.
Radio: Commercial radio stations did not come about until 1920. In 1913, the “wireless” was mainly used to send telegraphic messages in Morse code, not voice or music. After Congress passed the Radio Act of 1912 restricting private radio stations to wavelengths of 200 meters or shorter, which were considered useless, the number of radio hobbyists in the U.S. is estimated to have dropped by as much as 88%.
