Social Determinants of Health Data Collection (SDOH) in Hamilton during COVID-19
Health is influenced by a number of factors, including biology, access to health services, health behaviours, and the conditions in which people are born, grow, work, live, and age. These conditions are known as the social determinants of health, and include factors such as income, race, education/literacy, and gender. The social determinants of health can positively and negatively impact one’s ability to achieve good health. When health outcomes are patterned, unfair, and preventable, these are known as health inequities.
Hamilton is a diverse city and has a growing racialized population and a high proportion of people living with lower income. Evidence shows that racialized community members and lower income community members are disproportionately impacted by COVID-19 due to pre-existing health inequities. As a result, Hamilton Public Health Services (HPHS) began collecting social determinants of health data from COVID-19 cases to better understand COVID-19 disease prevalence in the community. HPHS also uses Public Health Ontario data to help understand differences in vaccine uptake by race and income. Understanding if there are inequities in COVID-19 cases and vaccination rates helps create focused interventions to reduce the risk of COVID-19 infection and support vaccine uptake.
- Hamilton Public Health Services (HPHS) has collected SDOH data on COVID-19 cases since May 26, 2020. HPHS retrospectively collected SDOH data on cases occurring prior to May 26, 2020.
- SDOH data collection was temporarily paused in Wave 2 (January – February 2021) and during the Omicron wave (starting December 2021) in order to ensure all cases and high-risk contacts were reached quickly enough to slow virus spread.
- Data collected includes race, language, household income, household size and Indigenous identity.
- HPHS has analysed SDOH data for Hamilton’s COVID-19 cases at two time points (October 2020 and June 2021). The trends presented below have been stable since October 2020.
- Trends in Hamilton’s SDOH case data are consistent with trends described by other regions and in provincial reports.
Summary of Findings
- Nearly half (45%) of Hamilton’s COVID-19 cases were racialized people. This shows racialized people were disproportionately impacted by COVID-19 since racialized people only make up 19% of Hamilton’s population.
- 25% of COVID-19 cases lived in low-income households. This shows that low-income households were disproportionately impacted by COVID-19 since this population only makes up 19% of Hamilton’s population
- These results are provided by Hamilton Public Health Services by collecting socio-economic data directly from COVID-19 cases.
- Local data should be interpreted with caution, as data are not representative of all COVID-19 cases. This is because HPHS can only share responses from those who provided this information, which would exclude those who chose not to participate, those who were not asked because of changes to the HPHS data collection processes, or cases that were not reported to public health. While HPHS used reliable data (the 2016 census) to determine the proportion of residents who are racialized or low income, these data are dated. However, results from HPHS sociodemographic analysis of COVID-19 cases are consistent with other jurisdictions, which similarly have found that racialized and low-income populations are disproportionately impacted by COVID-19 infection.
Impact of SDOH Data on COVID Response
The SDOH data findings led to and/or reinforced the importance of many local initiatives for racialized people and those living with low income. Some examples include:
- Delivery of essential supplies (e.g., groceries, medications) to isolated individuals without adequate social supports.
- Consultation and support to Indigenous organizations to establish an Indigenous-led COVID-19 call centre and Indigenous-led vaccine clinics.
- Consultation and support to organizations and leaders to establish community vaccine clinics for Black and racialized people.
- Enhanced infection control support in congregate settings such as residential care facilities and temporary farm worker housing.
- Mobile COVID-19 testing and vaccination options in priority neighbourhoods, including homebound options for non-ambulatory residents.
- Support provided to shelters about public health measures to reduce transmission.
- Prioritization of shelter populations for COVID-19 vaccination.
- Designation of two additional “Hot Spot” areas in Hamilton, in addition to the “Hot Spots” defined by the Province.
- The additional “Hot Spots” were selected based on a high incidence of COVID-19 activity and a high proportion of racialized people, Indigenous people or people living with low income.
- Prioritization of Black and racialized people for COVID-19 vaccination, starting with those living in designated “Hot Spots”.
- Launch of a Vaccine Ambassador program to provide tailored and focused outreach to racialized communities in Hamilton.
- Funding for vaccine outreach granted to community organizations working with priority populations.
- Hamilton Public Health Services uses Public Health Ontario’s (PHO) ecological analysis of SDOH data for vaccinations. The PHO analysis combines vaccine coverage data with neighbourhood-level measures of diversity and material deprivation collected through the census.
The latest analysis of socio-economic status of vaccinated Hamiltonians (January 2022) found:
- At the beginning of the vaccine rollout, neighbourhoods with more racialized populations had lower vaccine rates. Over time, this gap closed and currently the neighbourhoods with more racialized populations have a similar vaccination rate (83.5% with at least 1 dose) compared to the least racialized neighbourhoods (83.2% with at least 1 dose).
Date | Low Diversity Neighbourhoods | High Diversity Neighbourhoods |
---|---|---|
29-May-21 | 67.4% | 58.2% |
19-Jun-21 | 75.1% | 68.2% |
31-Jul-21 | 79.4% | 74.6% |
28-Aug-21 | 79.4% | 79.1% |
26-Sep-21 | 82.2% | 83.4% |
24-Oct-21 | 83.5% | 85.9% |
21-Nov-21 | 84.4% | 87.3% |
02-Jan-22 | 83.2% | 83.5% |
-
As of January 2022, neighbourhoods with the highest poverty (material deprivation) rates have lower vaccine rates (75.8% with at least 1 dose) compared to neighbourhoods with the lowest poverty rates (87.1% with at least 1 dose); however, this gap has narrowed since May 2021.
Date | Low Material Deprivation Neighbourhoods | High Material Deprivation Neighbourhoods |
---|---|---|
29-May-21 | 69.4% | 50.9% |
19-Jun-21 | 76.8% | 61.2% |
31-Jul-21 | 80.4% | 68.4% |
28-Aug-21 | 84.0% | 70.9% |

Impact of SDOH Vaccination Data on COVID Response
- Similar to the SDOH data findings on COVID-19 cases, the ecological analysis reinforced the need to provide focused outreach for racialized people and those living with low income through the Vaccine Ambassador program and the vaccine outreach funding provided to community organizations. In addition, these data support selecting locations for both fixed and mobile vaccine clinics by placing clinics in locations that are accessible and in or near priority neighbourhoods.
- The closing of the vaccination rate gap between neighbourhoods with the lowest and highest levels of diversity provides evidence that the efforts by community organizations, health care partners, and public health to increase uptake have been successful. Continued effort is needed to increase vaccination rates in low-income neighbourhoods.
