Phase 3 (NVI Survey)

Phase 3 (Behavioral Risk Factor Surveillance System (BRFSS) survey modules)

Being able to validate the NVI survey data with the nationally developed BRFSS survey, we noticed two important details from over 400 NVI survey respondents who completed the two additional modules (Reactions to Racism and Social Determinants of Health):

Methodology

See History for a description of the process to decide which indicators would be part of the Neighborhood Vitality Index.

There are two distinct types of indicators included in the Neighborhood Vitality Index: primary (data collected through resident surveys) and secondary (data from a variety of existing administrative sources). The data presented in the current tool is from Phase 3 of the pilot process, with primary data from 2,463 Detroit residents. Due to the number of responses, we are sharing data at the City Council District-level, and since there are only seven Council Districts the overall index was not calculated for the current tool. After a year of full implementation (beginning in 2024), we expect to gather enough resident survey responses to present data at the Neighborhood Zone-level with indexing.

Primary Data

Primary data collection in Phase 3 consisted of a survey of Detroit residents launched in February, 2023. Eligibility criteria were based on age (18 years of age or older) and residence (primary residence in the city of Detroit; some exceptions were made in this phase for residents of Hamtramck and Highland Park though responses outside Detroit are not included in this tool). Eligible residents who completed the survey were provided $25 Visa gift cards to compensate them for their time and sharing information. Gift cards were limited to one per person, and duplicate surveys from residents who had already completed the survey once were disqualified.

The Phase 3 survey was largely the same as the survey tested in previous phases, with minor additions. Spanish and Arabic translations of the survey were made available online or on paper if requested. The median time to complete the survey was between 16 and 17 minutes.

The Phase 3 survey was implemented in two phases. Phase 3A would continue the random sampling design of Phase 2 at a city-wide scale, but to save resources and allow for changes to plans later, only a portion of the required sample size was initially invited. More than 4,500 Detroit households were sampled and invited via mail to participate in the survey. Though the sample was intended to exclude vacant properties, a small number of invitation packets were returned by USPS.

The mailed invitation packet was packaged in an attractive 9x12” envelope containing a letter from CDAD with instructions to participate online, a paper version of the survey , and a self-addressed, stamped envelope to return the paper survey. Household identification numbers were included to allow the survey team to track online responses from each household. The letter also provided Spanish and Arabic translations of the survey instructions. A phone number and email address were provided for questions or requests to take the survey over the phone. The households that did not immediately respond to the survey and for whom mail was not returned were sent reminder postcards a few weeks later. Phase 3A remained open until June, during which time 408 complete surveys were collected for a response rate of approximately 8%.

Given the pace of survey responses in 3A and projections of the resources and time that would be required to meet the sample goal, the survey team pivoted to a new strategy based on lessons learned through Phase 1 and Phase 2. In Phase 3B, the survey was opened to all residents of Detroit 18 years or older, regardless of where they lived in the city and without a personal invitation. The representativeness of the resulting sample would be determined through data analysis after the survey closed. By opening the survey to the whole city, outreach became simpler and was able to leverage the relationships with the CDOs that the NVI team developed over the last 7 years. Now the message would pertain to all residents of Detroit 18 or over, as opposed to “watch for an invitation in your mailbox.” Phase 3B outreach efforts included traditional media, social media, text message campaigns, and community engagement. More than 50,000 flyers were distributed to community members at local events, libraries, local businesses, and through the Rocket Community Fund’s Neighbor to Neighbor canvassing.

A drawback of the 3B approach with an online survey was an influx of responses from bots or spammers around the world. The survey team needed to verify that each complete survey response was eligible by contacting respondents. After verifying thousands of responses, the cumulative sample across 3A and 3B included 2,526 eligible complete surveys.

Survey respondents were asked to provide a valid current address in the City of Detroit. These addresses were geocoded and resulted in 2,463 matches within the City of Detroit. Responses were then tagged with Council Districts and indicators were aggregated based on the criteria in the data dictionary.

Secondary Data

Secondary data processing derived from two main sources: the American Community Survey (ACS) and Data Driven Detroit’s Integrated Property Data System (IPDS). ACS data was downloaded from data.census.gov at either the census block group or census tract level, and aggregated to City Council Districts. IPDS data was extracted at the parcel level and aggregated to City Council Districts. Indicator details are included in the data dictionary.
