For single indicators, this represents the value in the corresponding unit. For the Composite Index, the value is derived following the CDC Social Vulnerability Index (SVI) methodology. If a weight (WGT) of -1 is applied, the opposite of the indicator is used in the index computation.
This is derived by dividing the margin of error (MOE) of the indicator by its estimate. MOEs are provided by Census.org or computed as the standard deviation of the estimate.
This is measured by the complement to 1 of the Relative Standard error (RSE) to the estimate. High reliability: REL >= 80 (● green). Medium reliability: 60 <= REL < 80 (● orange). Low reliability: CV > 60 (● red).
Neighborhood boundaries overlap, and some neighborhoods extend beyond Portland city limits. Some areas within Portland city limits are not claimed by a neighborhood association. For these reasons, the sum of the population of all neighborhoods does not equal the city total.
Population & race/ethnicity, housing units/households, vacancy rate and household size for 2010 and 2020 from decennial U.S. Census; additional indicators from 2017-2021 5-year ACS, based on proportional allocation of census tract data to census blocks, and of census blocks to neighborhoods (see methodology report).
Rent burdened households spend ≥30% of income on rent (≥50% indicates severely burdened). Crowded means >1 occupants per room (>1.5 indicates severely crowded).
For race/ethnicity "alone or in combination", each multiple-race person is counted multiple times (once for each self-identified race). Sum of "total races tallied" therefore exceeds total population.
Diversity Index is the chance that two randomly selected persons are of a different race/ethnicity.
Rent burdened households spend ≥30% of income on rent (≥50% indicates severely burdened). Crowded means >1 occupants per room (>1.5 indicates severely crowded).
Food insecurity refers to predicted lack of reliable access to nutritionally adequate foods.
Disability includes non-institutionalized persons who have self-reported difficulties in one or more of: hearing, vision, cognitive, ambulatory, self-care, or independent living.
SVT is an assessment of communities' access to emergency services and programs before, during, and after disasters. Higher number indicates higher vulnerability.
LEP means speaking English less than "very well". Not all languages spoken in Portland are represented in the data. More information at portland.gov/officeofequity/language-access/.
Neighborhood profiles are a project of the City of Portland Office of Civic Life, in partnership with the Portland State University Population Research Center.
