HBHC early childhood period

From six weeks of age to six years of age.

HBHC postpartum period

From the infant’s birth up to six weeks of age.

Health Indicator Framework

Health indicators are used to measure health status of a given population over a defined period of time. For this resource, appropriate indicators were chosen from the Core Indicators for Public Health in Ontario – a framework developed by the Association of Public Health Epidemiologists of Ontario (APHEO). This framework was developed, and it continues to be updated, in order to standardize and improve the accuracy of community health status reporting across Ontario public health units.  This resource provides definitions, methods and resources for calculating over 120 health indicators. Local level, reliable data was unavailable for some indicators therefore, not all were addressed in this resource. 

Heavy drinking

Monthly occurrences of drinking 5 or more standard drinks on any single occasion.

High birth weight rate

The number of live births with a birth weight of 4,500 grams or more, per 100 live births.

Home Language

The language spoken most often at home

Household food security

the financial ability of households to access adequate food. Insecurity included marginal, moderate and severe food insecurity.

Housing Affordability

Spending more than 30% of the household income on housing costs like rent or mortgage payments, property taxes and utilities can leave people without enough money for other important necessities like food, clothing and transportation.

How was SES determined in the Gaps in Health based on Socioeconomic Status section?

Socioeconomic status (SES) was based on a deprivation index composed of the following factors: percent without high school diploma, percent employed, average income, percent of single-parent families, percent of persons living alone, and percent of persons separated, divorced or widowed.


Immigrants are people who are or who have ever been landed immigrants or permanent residents. Such persons have been granted the right to live in Canada permanently by immigration authorities. Immigrants who have obtained Canadian citizenship by naturalization are included in this category.

Immunization coverage

“Immunization coverage refers to the proportion of a defined population that is appropriately immunized against a specific vaccine-preventable disease (VPD) at a point in time”2 .

Student immunization coverage is usually expressed as a percent, and can be calculated for a variety of populations of interest: within a particular grade in a school, for an entire school, or across an entire region. As immunization coverage values increase, the greater the proportion of people in the population of interest who are appropriately immunized, and therefore considered to have protection from the vaccine-preventable disease of interest.

Assessment of whether or not students are appropriately immunized is based on whether they have received the immunizations indicated in the Publicly Funded Immunization Schedules for Ontario at the appropriate age and time intervals.

Immunization of School Pupils Act

The Immunization of School Pupils Act (ISPA) is the Ontario legislation that outlines the responsibilities of Ontario public health units to maintain immunization records for students attending schools in their jurisdictions, and to assess those records to ensure that students are appropriately immunized against designated vaccine-preventable diseases of public health significance. Under the ISPA, students whose immunization records are not up-to-date for designated diseases may be suspended from school. Those who have had the disease of interest or who have medical reasons for being unimmunized against ISPA-designated diseases can submit a Statement of Medical Exemption. Those who have philosophical or religious reasons for being unimmunized can submit a Statement of Conscience or Religious Belief.

Immunization Records Information System (IRIS)

IRIS is the information system used by all Ontario health units in Ontario to record immunizations and exemptions for all students attending school within the health unit jurisdiction, as well as children attending licensed day cares.  The database is maintained by the Ministry of Health and Long-Term Care and individual health units.

Impact of Health Problems

This is a crude measure of the impact of long-term physical conditions, mental conditions and health problems on the principal domains of life: home, work, school, and other activities.

Incidence Rate

The rate at which new events occur in the population in the given time period

Income quintile

This is a measure that divides the entire population into five equal groups, also known as quintiles. Approximately 20% of the population is in each group. The lowest income quintile is the group with the lowest total household income, after taxes.

Income share

is one way to look at income inequality. It is the share of income held by the half of all households whose incomes fall below the median household income. A percent of 0% would represent complete inequality and a percent of 50% would represent equality.

Index of Socioeconomic Distress in Maps

The socioeconomic distress index, developed at Human Environments Analysis Laboratory at Western University, takes into account four factors: highest level of completed education, unemployment rate, lone parenthood rate, and low income rate. Greater composite scores correspond to higher levels of socioeconomic distress.
