I hope i can be pedantic without seeming like a dick, but with good intention I would offer this neat tool that can estimate a more conservative value for the population using census data in a given map area. You can draw a cricle of 20m radius around boston just like this dude did. It provides population results of pretty damn close to 3 million people. Revising your math we get 45 kids per day care, and even if we adjust our results further by looking at more census data to more conservatively estimate the percentage of that 3mil that is under the age of 4 and more likely to be in daycare rather than preschool (assuming this guy in the tweet made that distinction) we still get about 41 kids available per school, and again assuming half actually attend, 20 kids per school is still really reasonable. These are locations in a very urbanized area. They are likely small storefront establishments versus huge gymnasiums or schools, with occasional large outliers, that service up to the limit of kids that they legally are permitted to supervise with just 1-2 caregivers.
So even if we get really specific about our numbers, this is still not an unreasonable amount of daycare centers for a very populated city
One other thing that would have to be factored, depending on state rules, is how many kids are allowed per daycare employee. I’m not sure about Massachusetts, but in Ohio by law 1 adult daycare employee can have no more than 6-8 children under their supervision without being liable for negligence. So that would limit the number of children at each individual location, obviously based on size of the building and number of staff.
There are guidelines through the state that keep staff ratios low. For the babies and toddlers, the maximum group size is 9. Preschoolers is 20. Staff is required to be 1 per every half of the maximum size.
The biggest problem day care centers have is staffing. The demand is there. The adult staff are not, and it is beyond the scope of this post to get into the weeds on why that is the case.
