Erin sits at City Score rank #91 with a standing of 55%, from 5 of 8 open-data pillars (tax, construction, connectivity, indoor air, water, seismic hazard, growth, safety). Missing pillars score at median standing so thin coverage cannot inflate the rank. Rising 23 places versus 2022 (#114 → #91).
Latest owned placements: indoor radon rank #138 of 327 at 106 Bq/m³ survey mean. Full tables and method notes live on each study edition; atlas readings for the same slug open from the topic buttons.

Erin lands on the Ontario map as a place people still call home.
Erin grew the familiar Canadian way: schools, rinks, churches, and a main street that still anchors weekends. Ask three locals which decade mattered most and you will get three different answers, all delivered with a grin.
Erin service economy ties to county seats, highway corridors, and regional employers that keep main street businesses busy through the year. On OpenStats City Score, Erin ranks 128 of 343. Municipal recreation, parks, trails, and utility pages remain the best live guide to how Erin explains itself today.
Permits, mill rates, broadband, radon, hazards, and water quality may show measured values, regional estimates, or empty states until a verified source is linked. That is the same honest pattern OpenStats uses for smaller places already in the corpus, and it keeps Erin comparable on the hometown board without inventing numbers. Seasonal recreation programming, winter maintenance, and summer festival calendars still fill the municipal news feed most years. Library branches, arena ice, and aquatics schedules are the practical anchors families check before planning a weekend in Erin.

City Score from 2016–2025 across eight open-data pillars. Individual study placements are listed in the panels below.
Each study below is its own ranking. Where a study has more than one edition for this city, the chart shows standing across those years only.
Safety · OpenStats
Statistics Canada does not publish a police-service Crime Severity Index that OpenStats can match to Erin without copying a province, CMA, or another city. The safety pillar scores at median standing (50%) on City Score, the same rule used for other missing pillars.
Connectivity · OpenStats
OpenStats
Cities ranked by household-weighted maximum advertised download (Mbps) from ISED National Broadband Data hex ISP rows, with hex-to-city assignment by population-weighted gravity. The headline 2025 score is the dwelling-weighted mean of per-hex technology ceilings (fibre and cable at 1 Gbps, DSL lower). Household-weighted 50/10 availability (%) is stored on atlas rows as avail_5010_pct. Earlier panel years backcast along a national speed curve with city-specific fiber and availability paths.

Composite · OpenStats
OpenStats
Dimensional average of OpenStats open-data pillars for each panel year 2016-2025: tax, construction, connectivity, indoor air, water, seismic hazard, population growth, and crime severity. Each series is scored 0-1 within its edition; series in the same pillar are averaged, then all eight pillars are averaged with equal weight. Missing pillars score at median standing (0.5). Crime severity uses StatCan police-service CSI only (Tables 35-10-0026-01 and 35-10-0063-01); cities without a police-service match take median standing on the safety pillar. Growth uses StatCan CSD estimates; construction uses verified municipal building-permit value per resident (population field on each city record, 2021 Census vintage); mill rates and broadband use live rows plus documented year-varying estimates where needed. Radon, water, and PGA may be survey/model vintages carried forward and are flagged when static for more than two years. External commercial livability lists are never inputs.

Communities ranked by municipal drinking-water hardness (mg/L as CaCO₃). Hardness changes slowly; the atlas vintage is carried across panel years and flagged when static for more than two years.

Health · OpenStats
OpenStats
Communities ranked by Health Canada survey mean indoor radon (Bq/m³). Rank 1 is the highest mean. Decade panel years without a new survey carry the CMA survey vintage forward; they are not annual retests.

Growth · OpenStats
OpenStats
Cities ranked by year-over-year population growth from Statistics Canada annual CSD estimates (Table 17-10-0155-01). Rank 1 is fastest growth. A few places without a clean CSD match use a provincial-path estimate anchored to seed population.

Hazards · OpenStats
OpenStats
Communities ranked by NRCan peak ground acceleration (higher = stronger shaking hazard). Rank 1 is highest PGA. The seismic model is multi-year; values are carried across the City Score panel and flagged as static until NRCan publishes a new generation.
