Every decade America gears up for the census. Every household is mailed the 10 questionnaire page to fill out. This year we must do the same thing, or else you'll be hounded by the minions of the census bureau coming to your abode.
This isn't a new practice either! The United States has been having their citizens fill out this form for over 200 years, although I am sure they've changed some. The first census of 1790 tells us how many people were living in the United States. The results may surprise you.
The population was 3,929,326 people. That is about the same amount as the population of Los Angeles today.
Our metropolises of the east coast were already metropolises then too. They just couldn't boast the same numbers we have today. When the censuses were added up, these were the populations of those cities:
New York City: 33,000 (8,400,000)
Philadelphia: 28,000 (1,500,000)
Boston: 18,000 (600,000)
Charleston: 16,000 (127,000)
Baltimore: 13,000 (638,000)
200 years does allow ample time for cities to grow! I put the modern populations in the parentheses for you to compare. So when that annoying little envelope comes around in the mail you should find it your historic duty to fill it out!
