But Klausner said that because it is important to link NCI with other data sources--such as the Census Bureau, Medicare records, and state health department records--NCI can't break away from existing population categories on its own.
Of the various population categories, based on the demographic history and number of generations of admixture, the African American controls are expected to be in Hardy Weinberg equilibrium, as has been demonstrated previously (5).
Moreover, there are three transitions between such population categories.
Incidence numbers provided in our report are based on population numbers for each age category, based on www.statistikbanken.dk.statistikbanken.dk
Although it is not stated clearly in Thorlund's article, we assume that the incidences are based on population numbers for each age category and not for the whole population.
One of the products that eventually came forth was ARIA+, a system that creates an index, with values ranging from 0 (high accessibility) to 15 (high remoteness), based on road distance measurements from over 12,000 populated localities to the nearest urban areas in five categories based on population size.
ARIA is a continuous varying index with values ranging from 0 (high accessibility) to 15 (high remoteness), and is based on road distance measurements from over 12,000 populated localities to the nearest Service Centres in five size categories based on population size.
The Livestock Conservancy maintains a conservation priority list that divides endangered breeds of horses, asses, sheep, goats, cattle, rabbits, pigs and poultry into five categories based on population numbers and historical interest.
The degree of urbanization of the patients' residence (five categories, based on population density per postal code area), obtained from Statistics Netherlands, was also linked to the database [ 26].
Residential location was measured using the Rural, Remote and Metropolitan Areas RRMAA) classification, which is an index based on Statistical Local Areas (SLA) that allocates each SLA in Australia to a category based primarily on population numbers and an index of remoteness.
Urban areas were divided into three categories, namely, large, medium, and small, based on population size.
