Population - Rates calculated using July 1 population estimates from the
Florida Legislature, Office of Economic and Demographic Research. The population
data for 2001-2010, along with rates affected by the population data, has been updated
on Florida CHARTS. Following a census, it is customary to revise population projections
for the intercensal years based on information from the latest census. Revising
the population data from what was predicted to actual estimates ensures accurate
accounting of the racial, ethnic, and gender distribution of the population. These
changes affect the population data and rates calculated for your community.
Year - (SY) = School Year. Other time periods include single calendar years
(ex. 2006) and three-year averages (ex. 2004-06).
Quartiles - Quartiles in this report allow you to compare health data from
one county to another in the state. Quartiles are calculated by ordering a rate
from most favorable to least favorable by county and dividing the list into 4 equal-size
groups. In this report, a low quartile number (1) always represents more favorable
health situations while fours (4) represent less favorable situations. Blanks in
this column indicate that not enough data was available to calcuate a quartile or
that a quartile calculation was not appropriate (i.e. population counts). Quartiles
for rates from the YRBS, FYTS, and FYSAS surveys are based on fewer than 67 counties
as some counties did not participate.
Counts - Counts for indicators displaying a 3-year rate are an average count
of events over 3 years, NOT a sum. Blank spaces in this column indicate that no
count is available for the indicator. A count of "<1" indicates an average of less
than 1 event per year over a 3 year period.
U = Unstable rate (based on fewer than 5 events). When the rates are based
on only a few cases or deaths, it is almost impossible to distinguish random fluctuation
from true changes in the underlying risk of disease or injury. Therefore comparisons
over time or between communities that are based on unstable rates can lead to erroneous
conclusions about differences in risk which may or may not be valid.
1Total population minus the sum total of white and black populations
results in the other nonwhite population count. TOTAL - (WHITE+BLACK) = OTHER NONWHITE.
2The Census Bureau defines a linguistically isolated household as one
in which no one 14 years old and over speaks only English or speaks a non-English
language and speaks English "very well." In other words, all members of the household
14 years old and over have at least some difficulty with English.
3Modifiable behaviors leading to premature death are the major external
(nongenetic) factors that contribute to death in the US, first identified as "Actual
Causes of Death" by McGinnis and Foege in 1993. These three sets of behaviors each
contribute to over 100,000 deaths annually in addition to their impact on morbidity,
quality of life, and public health burden.
4Counties with < 10 HIV cases ages 13-19 do not have counts or rates
5Includes sexual battery, battery, homicide and kidnapping.
6Florida's high school graduation rate is the percentage of students
who graduated within four years of their initial enrollment in ninth grade, not
counting deceased students or students who transferred out to attend another public
school outside the system, a private school, a home education program, or an adult
education program. Incoming transfer students are included in the appropriate cohort
(the group whose progress is tracked) based on their grade level and year of entry.
7Potentially avoidable hospitalizations are those for which good outpatient
care can potentially prevent complications or more severe disease.
8n/a - For school districts with no nurses a nurse-student ratio cannot
