It’s hard to imagine a teenage culture in an economy where every 16-year-old is expected to work with his father on the lathe, or in the fields.The second key development in the creation of the teenager was the invention of cars.In a major city like Pittsburgh, In 1915, 100 million people lived in the United States, and more than half were under 25.One century later, the population is more than 300 million, but the share of people under age 25 has fallen to one-third.

Since the term applies to a group of youngish people who hang out together, their invention required an insulated environment where teens could behave, well, teenagery.Teens didn’t create "high school." High schools created “teenagers."As the U. economy shifted from a disparate agrarian society to a mass production machine, families relocated closer to cities and, at least initially, many sent their children to work.Women had more children—three, on average—to help on the farm in the old agrarian economy. For this happy and dramatic improvement, mothers and fathers can thank the professionalization of baby-delivery.But the more disquieting reason women had so many children was that children were likely to die: Ten percent of infants died in their first year, compared with one in every 168 births in the U. Giving birth at home in 1915 wasn’t merely normal; it was ubiquitous.America had one-third of its current population in 1915, and it was considerably more spread out.Half of all families lived in rural areas, or in towns with populations below 2,500.Carol Boyd Leon paints a sociological portrait of America as it was 100 years ago, when technology was meager, financial ruin was one downturn away, war was ongoing in Europe, and the choices that Americans have come to expect—in their cars, clothes, food, and homes—were preceded by a monotonous consumer economy.In 1915, Americans walked everywhere (or took a streetcar, if they lived in cities), lived in three-generation homes that they rarely owned, ate almost as much lard as chicken, and spent Friday nights dancing to player pianos.The movement to prevent kids from being forced to toil in mills encouraged compulsory education for teenagers.In 1920, just 28 percent of American youths between the ages of fourteen and seventeen were in high school.
