What is CAGR?
CAGR stands for Compound Annual Growth Rate and is represented within the data as a percent. Simply put, CAGR allows a clean presentation of data across multiple years
Technically CAGR is defined as: A business term representing the mean annualized growth rate for compounding values over a given time period. CAGR smooths the effect of volatility of periodic values that can render arithmetic means less meaningful. It is particularly useful to compare growth rates of various data values over time
How granular is the demographic data? Is it specific to each parcel?
The demographic data is not specific to each parcel. The demographic data is aggregated at the Census Block Group level which is the lowest level the US Census Bureau reports demographic data for and contains between 600 and 3,000 people (this represents between 250 and 550 housing units)
When is the demographic data Updated?
The demographic data is updated annually and is generally updated in late June or early July and reflects data from the previous year (for example, in July of 2024, the data is reflecting 2023 vintage data) Regrid performs backfill of the Demographic data to new parcels, created through our parcel update process, on a monthly basis.
