kindergarten teachers in US = 1. # kindergarteners in US divded by 2. # of kids in a class

1. # of kindergarteners in US = 300 million people in the US, let’s assume the population is evenly distributed by children, adults, senior, so 100 million children. out of 100 million, let’s assume 15% are kindergarteners.
15 million kindergarteners in US.
let’s assume there’s 30 kids in each class. 30 classes * 30 kids = 900 students in a school
If there are 15 million kindergarteners in the US, divide that by 30 kids in a class = 500,000
There are roughly 500,000 kindergarten teachers in the US. 

Population of US = 300 Mn

Assumption that 1/4 is population between 0 and 18 (based on a research report I read) = 75 Mn

Assuming these are equally spread across ages 0 to 18, 0 to 6 has 25 Mn kids, or roughtly 4 Mn kids / age ( 1 year band applicable for KG)

For every 25 kids there are 2 teachers typically and to account for all other suporting teachers, adding 1 so 3 teachers for every 25 kids ==> 12 teachers for every 100 Kids. =  4,000,000/100 * 12 = 480,000 = .48 Mn teachers.

As there are typically two sessions – morning and evening in a KG day of only 3 hours, half the number of teachers is sufficient. = .24 Mn teachers.

The population of USA is around 300 Million

People generally live upto 75 years.

If we take equal distribution of all ages we get 4 million people in each age (1 to 75)

kindergarten is for kids with age less than 6  and more than 2 years  hence total 4*4 million  = 16 million

Each of the kindergarten may be operating in 2 shifts (morning and afternoon)

we will assume equal distribution of kindergarteners in morning and evening shifts

hence 8 million each.

each batch may be around 20 kids (as kids need more attention)

hence 8 million / 20 = .4 million

hence .4 million teachers.
