Three and a Half Years
That’s all it would take for Mormon missionaries to knock on every door in the US.
Don’t ask me why, but the question popped into my head one day: How long would it take for Mormon missionaries to knock on every door in the US? I finally sat down and did some “back of the napkin” estimates and came up with the following numbers:
Total Households in 2010 = 114,235,996
Total Households minus Mormon households = 112,735,996 (subtracted 1.5 million households)
Missionaries = 20,000
Households Knocked per Day = 10
Days to Knock Every Household = 1,127
Years to Knock Every Household (including p-days) = 3.602
I have no idea why or how this information would be useful, but I thought it was interesting. Here’s the spreadsheetI used to make the calculations in case anyone wants to fiddle with the numbers.
