Data tables for ONS Neighbourhood COVID-19 Maps (Historical)

Cumulative and monthly counts and rates of confirmed COVID-19 in Ottawa neighbourhoods, excluding cases linked to outbreaks in long-term care homes (LTCH) and retirement homes (RH). Based on the most up to date information available at 2pm from the COVID-19 Ottawa Database (The COD) on the day the data is pulled to provide the monthly update. Accuracy: Points of consideration for interpretation of the data: Data extracted by Ottawa Public Health at 2pm from the COVID-19 Ottawa Database (The COD) the day prior to publication. The COD is a dynamic disease reporting system that allow for continuous updates of case information. These data are a snapshot in time, reflect the most accurate information that OPH has at the time of reporting, and the numbers may differ from other sources. A case (an individual with laboratory-confirmed COVID-19 infection) is assigned to an Ottawa Neighbourhood Study (ONS) geography based on the individual’s residential postal code and the ONS’s postal code conversion file. As the area served by a given postal code may cross multiple neighbourhoods, the ONS postal code conversion file identifies the proportion of each postal code that falls within a neighbourhood. Thus, for cases with postal codes falling within multiple neighbourhoods, a fraction of those cases will be assigned to each neighbourhood. Rates calculated from very low case numbers or for neighbourhoods with very small populations are unstable and should be interpreted with caution. Low case counts have very wide 95% confidence intervals, which are the lower and upper limit within which the true rate lies 95% of the time. A narrow confidence interval leads to a more precise estimate and a wider confidence interval leads to a less precise estimate. In other words, rates calculated from very low case numbers fluctuate so much that we cannot use them to compare different areas or make predictions over time. Update Frequency: Monthly Attributes: Data fields ONS Neighbourhood – text Cumulative rate (per 100 000 population), excluding cases linked to outbreaks in LTCH and RH – cumulative number of residents with confirmed COVID-19 in a neighbourhood, excluding those linked to outbreaks in LTCH and RH, divided by the total population of that neighbourhood Cumulative number of cases, excluding cases linked to outbreaks in LTCH and RH - cumulative number of residents with confirmed COVID-19 in a neighbourhood, excluding cases linked to outbreaks in LTCH and RH Monthly rates (per 100 000 population), excluding cases linked to outbreaks in LTCH and RH –number of residents with confirmed COVID-19 in a neighbourhood reported to OPH during the month of interest, excluding those linked to outbreaks in LTCH and RH, divided by the total population of that neighbourhood. Monthly number of cases reported, excluding cases linked to outbreaks in LTCH and RH - number of residents with confirmed COVID-19 in a neighbourhood reported to OPH during the month of interest, excluding cases linked to outbreaks in LTCH and RH.
