The side-by-side above pulls the the DOL National Database of Childcare Prices data for both entity A and entity B. What follows is the interpretation — which specific axes carry the most weight for entity A versus entity B, and which differences are large enough to influence a real decision.
Practical use of the comparison: read the data above, then drill into the individual entity A and entity B detail pages for the underlying breakdown. A pairwise comparison answers the relative question; the per-entity pages answer the absolute question.
