Metro values are the Census Bureau's own metro estimates, except five-year population growth, which is pooled from the member counties because metro definitions change between surveys. |

## Measures

The key is the measure's identifier in Cadastre. A measure stored for the metro itself is read as stored; **Rule from counties** is how a metro is assembled from its counties where it is not (see [Methodology](https://getcadastre.com/docs/methodology)).

| Key | Label | Unit | Rule from counties |
| --- | --- | --- | --- |
| `population_growth_5yr` | Five-year population growth | percent over 5 years | growth of member counties combined |
| `population` | Population | people | sum over member counties |
| `median_household_income` | Median household income | dollars | Not assembled from counties: a metro has a value only where one is stored for the metro itself |
| `median_home_value` | Median home value | dollars | Not assembled from counties: a metro has a value only where one is stored for the metro itself |
| `education_high_school_rate` | Adults whose highest education is high school | percent of adults 25+ | population-weighted county mean |
| `education_some_college_rate` | Adults whose highest education is some college | percent of adults 25+ | population-weighted county mean |
| `education_associate_rate` | Adults whose highest education is an associate degree | percent of adults 25+ | population-weighted county mean |
| `education_bachelor_rate` | Adults whose highest education is a bachelor's degree | percent of adults 25+ | population-weighted county mean |
| `education_graduate_rate` | Adults whose highest education is a graduate degree | percent of adults 25+ | population-weighted county mean |
| `household_poverty_rate` | Household poverty rate | percent of households | population-weighted county mean |
| `severe_rent_burden_rate` | Severe rent burden rate | percent of renter households | population-weighted county mean |

## Known gaps and caveats

- Medians are never averaged across counties: a population-weighted mean of medians is not a median of anything, so a median is shown only where the Census Bureau publishes it.
- Educational attainment shares are by highest level reached, so they do not overlap.
- Connecticut replaced its eight counties with nine planning regions, which Census geography now uses; for growth, the prior population of each planning region is rebuilt from its towns.
