Read all the notes above and below the table to be sure you are correctly interpreting the data within the table. Numbers in the table are often expressed in units of 100, 1000, or more, multiplying the number in the table by that unit for the total number. Footnotes provide further explanation or note exceptions.
The source of the data is also indicated at the bottom of the table and may be consulted for further information.
Statistical Terms Defined
rate: A rate refers to the occurrence of events over a specific interval in time. Similarly, a rate refers to the measure of the frequency of some phenomenon of interest.
Often seen as mortality rate (number of deaths per unit (often per 1000) in a given year) or as incidence rate (number of new cases of a disease per unit in a given time frame).
ratio: A ratio is a number that expresses the relative size of two other numbers. The result of dividing a number X by another number Y is the ratio of X to Y.
The closer to 1, the more similar X and Y are.
It may be easiest to find statistics on the most common diseases in a population, leading causes of death, or communicable diseases required to be reported to health agencies. However, common behavioral risk factors may be indicators of a wide range of diseases and conditions and are an additional source of statistics. Statistics on cause of death may also be easier to locate that incidence or prevalence among the general population.
