Saturation ranking

Where child day care services is most and least saturated in California

Every California market with sourced Childcare data, ranked on how much provision it already has. Counties are measured per 10,000 residents. Cities are measured as a share of the businesses in the same ZIP codes, because a city’s establishment counts cover its ZIP codes rather than its city limits and cannot be divided by its municipal population. Neither measure says anything about revenue or profitability, and a crowded market is not automatically a bad one: it is also where the most businesses come up for sale.

Most saturated counties for childcare

51 of 53 counties with sourced data qualify for this ranking. Markets with fewer than 5 establishments are excluded at both levels, because a single opening or closing would move them enough to dominate the list. Counties under 2,000 residents are also excluded, where a per-capita figure is arithmetically true and analytically useless.

Most saturated cities for childcare

269 of 354 cities with sourced data qualify for this ranking. Markets with fewer than 5 establishments are excluded at both levels, because a single opening or closing would move them enough to dominate the list. Cities with fewer than 500 businesses in total are also excluded, because on a base that small the industry’s share moves on rounding.

Statewide, 0.90% of California businesses are in this industry. A higher local share means the industry takes up more of the local business base than it does statewide.

City figures are aggregated over the ZIP codes the Postal Service assigns to each place, which do not follow municipal boundaries. That is why the comparison here is a share of the businesses in those same ZIP codes rather than a figure per resident: both sides then cover the same ground, so a city that loses establishments to a separately named ZIP loses its denominator with them.

How to read these rankings

  • Both measures are supply measures. They say nothing about how much each business earns, how large it is, or how much demand comes from outside the market.
  • The two levels are not directly comparable to each other. A county figure is establishments per resident; a city figure is this industry’s share of the local business base against the statewide share. Compare counties to counties and cities to cities.
  • A thinly served market can be a genuine gap or a market already served from a neighbouring town. The individual market pages list the nearest comparable places for exactly this check.
  • A densely served market means competition, but it is also where the largest pool of existing businesses sits, and therefore where the most owners reach retirement each year.
  • Counties are the more stable measure. City figures rest on ZIP code geography, which the Postal Service redraws as it pleases, so a city can gain or lose a ZIP between years.
