1 Defining Neighbourhoods in Durham Region Mary-Anne Pietrusiak Epidemiology and Evaluation Unit Durham Region Health Department Agency for Health Protection and Promotion Workshop Public Health GIS Projects across Ontario November 30, 2009

2 Durham Region Located east of Toronto Population of about 600,000 Mix of urban, suburban and rural 8 Municipalities: Pickering, Ajax, Whitby, Oshawa, Clarington, Scugog, Uxbridge & Brock

4 The Need to Look Below Municipality More data available to us than ever before at the postal code level Differences between municipalities, differences within municipalities Better understanding our communities

5 Teen Pregnancy Durham Region and Ontario, Pregnancy rate in females aged Ontario Durham

7 Defining the Neighbourhoods We had no established neighbourhood-like groupings Sarah Maaten from ICES worked with us to the start project Our Regional GIS department did the actual mapping Reviewed processes of other health units Started by mapping 34 Census indicators by Dissemination Area (DA) & Census tract (CT) DA = small census unit with population of 400 to 700 persons CT = population of 2,500 to 8,000 persons in urban areas Map of low income was key We grouped DAs to create draft neighbourhoods that respected municipal boundaries, natural boundaries, major roads Aimed to have neighbourhoods of about 11,000 people, minimum 8,000

10 Finalizing the Health Neighbourhoods Tested draft neighbourhoods with health data: 1. Live births (hospitalization) Breastfeeding initiation (IFSS) Feb 2006-July Chlamydia cases in females (iphis) 2006 & Emergency department visits for injury (hospital ED) Were able to successfully map the data Sought input from Health Dept staff who know DR, plus municipal planners finalized boundaries & named the neighbourhoods Described in report on our website

11 Final Health Neighbourhoods 46 Health Neighbourhoods 2006 population size varies from 8,205 (Rural Uxbridge) to 18,470 (Lakeview) Average population 12,201

13 Health Neighbourhoods Project 1. Descriptive Maps 2. Socio-demographic Maps 3. Health Maps 4. Profiles

14 Descriptive Maps Provide context and information Show the boundaries and major features, e.g. roads, schools, parks Descriptive map for each health neighbourhood

15

16 Socio-Demographic Maps Eight socio-demographic indicators mapped: Population aged 19 and under Population 65+ Female lone-parent families Recent immigrants Visible minorities Population without high school diploma Unemployment Low income

27 Next Steps Map other health data Overweight/obesity or Healthy weight BF duration Injury by specific cause or age Vegetable & fruit consumption Use maps in our health status reports Create profiles for each neighbourhood

28 Creating Profiles UOIT student research practicum Determine how best to present the information: Tables of numbers with comparisons to Durham Region, maybe Ontario? Scale of Lower, Similar, Higher? Ranking? Descriptions to give a flavour of what that neighbourhood is like? E.g. fast growing, rural A Tale of Two Health Neighbourhoods

29 Neighbourhoods Ajax North West end of Durham Population 14,222 Residential Suburban community Growing fast Very high birth rate North Bowmanville East end of Durham Population 17,234 Residential Suburban community Moderate growth High birth rate Similar Neighbourhoods in Some Respects, Very Different in Others

30 Health Neighbourhood: Ajax North

31 Health Neighbourhood: North Bowmanville

34 Caveats Neighbourhoods are very diverse Danger of labelling neighbourhoods Postal codes don t necessarily go in cleanly, quality of postal codes 2006 population counts, no update until 2011 RRFSS data small numbers, lots of variability, need to use caution Need for interpretation, lead to more questions Need to educate ourselves and the public
