600,000 newspaper boys

DelanceyPlace.com has a selection from Little Merchants by Sandra Walker:

Children sold news sheets in Colonial times and, with the advent of the penny paper in 1833, even larger numbers became newspaper handlers. By 1962, there were six hundred thousand "paperboys", thanks in part to exemptions from Depression-era child labor laws for youths involved in distributing newspapers if they were at least twelve years of age. (The labor laws also exempted youths involved in acting, baby sitting, farm work, a family business, and making Christmas wreaths):
On 4 September 1833, Benjamin Day sent little urchins onto the crowded, bustling streets of New York City, into coffee houses and taverns, shouting and waving his new publication, the Sun newspaper. For one cent, men read the news sold to them on the spot. Day's successful paper spawned more penny newspaper businesses, until every crowded city teemed with hustling ragamuffms eager to earn a few coins selling sheets of news. Publishers could depend on an abundant supply of little merchants to call out the latest edition. The 'newsey' became a common American icon.
And Day's success increased. In five years the Sun had a circulation of thirty thousand, the largest in the world. As the 1830s ended and additional competitive publishers emerged, the newspaper business raced forward. Selling penny papers continued into the twentieth century. With the growing urban population, with electricity lighting city houses, the shift to the home delivery system increased. Residents appreciated their newspaper companion.
As Professor George Douglas explained in The Golden Age of the Newspaper: 'In the 1920s the American newspaper reached the pinnacle of its glory and influence'. This was a decade when public trust in journalists and editors excelled, when radio stations did not yet compete with publications. Douglas' statement expressed more than a narrow assessment of the number of papers sold, because three decades later, in the 1950s, the population soared to over a hundred and fifty million Americans, and total newspaper sales exploded as well. Actually, 1950 sales statistics state: 'increases more than twice as great percentage-wise as increases in the population'.
By the time children entered middle school, they acquired two or three jobs based on their paperroute experience. The first year-round job was augmented by seasonal work: picking berries, mowing lawns, harvesting apples, hauling coal, shoveling snow, all sandwiched between daily home chores.
In 1940, Henry McDaniel conducted a country-wide study of paperboys and their school progress for his Ph.D at Columbia University. He opened his dissertation with: 'Every day more than forty million newspapers, the world's most perishable commodity, are delivered to consumers. An army of three hundred and fifty thousand boys is involved in the high speed distribution.
The Tacoma News Tribune circulation office praised carriers at a banquet for Newspaperboy Day on 20 October 1962, as the national organization of circulation managers applauded America's six hundred thousand paperboys."
