Unless otherwise specified, all numbers and rates pertain to place of residence (not occurrence).

Ages are presented by Detailed Age Groups, Lifestages and Single Year of Age. Single year of age are created by Office of Health Indicators for Planning (OHIP), Department of Public Health. Also, note that selecting "all ages" will supersede any start and end age selection. Uncheck "all ages" to make an age-specific selection.
Hispanic or Latino includes persons of Mexican, Puerto Rican, Cuban, South or Central American, or other Spanish culture or origin, regardless of race.
Any county with 35,000 or more total population per year 2000 Census.
Population Estimates

Population data for years 1994-1999 are the National Center for Health Statistics Bridged-race estimates. These estimates were replaced by the Census' postcensal estimates on 1.12.04. However, single-year estimates were created from the actual Census count (enumeration), prepared by the U.S. Bureau of the Census. Documentation and file layouts are available from the U.S. Bureau of the Census web site.

Census populations include military, students, and institutionalized persons if in their usual and customary residence. The 2001-2009 Census postcensal estimates were replaced by the October 2012 release of the Census' intercensal estimates in November 2012. This Census release also contained new estimates of the 2000 and 2010 population and they too were updated in November 2012. Population estimates for year 2011 and beyond are postcensal estimates prepared by the U.S. Census Bureau, Population Division. Single year of age estimates are created by Office of Health Indicators for Planning (OHIP), Department of Public Health.

Percent of State Population

Percent of State population Answers what percent of the state population lives in the area chosen (stratified by Race and/or Age and/or Ethnicity and/or Sex if Race and/or Age and/or Ethnicity and/or Sex is chosen).

Percent Population by Race

If a race is chosen, Percent Population by Race answers what percentage of population in the area chosen is that race (stratified by Race and/or Age and/or Ethnicity and/or Sex if Race and/or Age and/or Ethnicity and/or Sex is chosen).

Per the Federal Office of Management and Budget, Directive 15 (1997),

Note: Rates for years prior to year 2000 use population estimates for the denominator that adhere to a different Federal standard for race: White, Black, Asian or Other Pacific Islander, American Indian and Alaska Native. So, unlike years 2000 and after, Multiracial is not included. Also, Asian by itself is not available because it was grouped with Pacific Islander (After 1999 Asian is separate from Native Hawaiian or Other Pacific Islander).

Rates using Census Population Estimates in the denominator are not calculated when a selected race is not available in the denominator, or zero.

Nevertheless, selections available in OASIS' Race query box reflect the 1997 Race classifications described above. Most of the numerators used in indicators in Oasis *do* have the year 2000 race selections. Therefore, selections of multiple years that span <2000 and 2000+ will return a *number (count)* for all race selections, but the *rates* may be limited by the change in racial classifications the federal government used as noted above. In these cases you will see NA1 in the output cell (NA1 therefore by definition will only show up in rates for the years before 2000).

In some cases, the numerator's race classification may be more precise, or up to date, than the Census population estimate counterpart used in the denominator. You may find that there are a number of births of a given race for a county/age-group selection, but no count of population estimated for the denominator. In such cases where the race selection was available for both the numerator and the denominator, but the denominator's estimate was zero, you will see a NA2. If the numerator was greater than the denominator, but the denominator was > 0, you will see a NA3 returned.

Any county with less than 35,000 total population per year 2000 Census.
