The study of components of variation and change in demographic variables and the relationships between them.
Demographic Analysis
The study of the relationships between demographic variables and other variables such as social and economic variables.
Population Study
It is a structure based on gender, race or other factors that can be inserted to.
Population Composition
The absolute number of a population or any demographic event occurring in a specified area in a specified time period.
Count
The relation of one population subgroup to the total population or to another subgroup; that is, one subgroup divided by another.
Ratio
The frequency of demographic events in population during a specified time period divided by the population “at risk” of the event occurring during that time period.
Rate
-70 new cases of breast cancer per 1,000 women per year*
-the proportion of people exposed to a particular risk factor who develop the health event over a defined period.
Attack Rate/Incidence Proportion/Risk
-20 or 130 persons developed diarrhea after attending a picnic.
- measures the frequency of new cases of a specific health event within a population at risk over a defined period.
Incidence Rate
-70 influenza case-patients in March 2019 reported in Taguig City.
- measures the total number of cases (both new and existing) of a health event in a population at a specific point in time.
Prevalence Rate
-2 deaths due to HIV in Pasay City.
-measures the proportion of individuals with a particular health condition who die as a result of that condition.
Case-fatality Rate
The relation of a population subgroup to the entire population; that is, a population subgroup divided by the entire population.
Proportion
An unchanging, arbitrary number by which rates, ratios, or proportions can be multiplied to express these measures in a more understandable fashion.
Constant
A statistic that measures events occurring to a COHORT (a group of people sharing a common demographic experience) who are observed through time.
Cohort Measure
A statistic that measures events occurring to all or part of a population during one period of time.
Period Measure
Sources of Population Data
Census
Sample registration survey
Registration of live events
Institutional records
It is defined as branch of biometry which deals with data and the law of human mortality, morbidity and demography‖. These are collected, compiled and then analyse.
Vital Statistics
the total process of collecting, compiling and publishing demographic, economic and social data pertaining at a specified time or times, to all persons in a country or delimited territory. It has ten years interval
Census
(in fact, whether by right or not) - the method is to list all persons present in the household or other living quarters at midnight of the census day or all who passed the night there.
De facto census
(by right) - all persons who usually live in the household are listed on the form whether they are present or not. Visitors who have a usual residence elsewhere are excluded from the listing but are counted at their usual residence.
De jure census
each individual is enumerated separately and characteristics of each person are recorded separately. The census covers a precisely defined territory and includes every person present or residing within its scope. defined reference period. q The census is taken at regular intervals.
Modern census
These are used when these changes cannot be measured directly, as for example health or nutritional status. If measured sequentially over time they can indicate direction and speed of change and serves to compare different areas and groups of people at the same moment in time.
Health Indicators
They should actually measure what they are supposed to measure
Valid
The answers should be the same if measured by different people in similar circumstances.
Reliable
They should be sensitive in the situation concerned
Sensitive
