Valley: Income below 200% poverty level NOTE: The ACS data are estimates based on a five-year average, meaning that data gathered from 2017, 2018, 2019, 2020, and 2021 are averaged together to come up with the results shown here. There is no problem with comparing these data to census data from 2000.
