Population and demography are major areas of study for social scientists. A population is defined as a group of individuals occupying a particular place at a given time. Key factors in defining a population are group, place, and time. Population growth impacts issues like housing, food security, and the environment. Demography statistically analyzes population characteristics like size, composition by age and sex, birth and death rates, and immigration. Demographic data is important for policymaking and predicting future trends. Sources of demographic data include censuses, vital statistics like birth and death records, and surveys. Population change is influenced by fertility, mortality, and migration. Population pyramids display the age and sex structure of a population.

5. PLACE

8. DEMOGRAPHY IS THE STATISTICAL ANALYSIS AND DESCRITION OF POPULATION AGGREGATES WITH REFERENCE TO THE DISTRIBUTION, VITAL STATISTICS, AGE, SEX AND RELATED FACTORS

9. THE SCIENCE OF DEMOGRAPHY LOOKS ALSO INTO FACTORS THAT MAY CAUSE POPULATION TO INCREASE OR DECREASE IN ANY GIVEN AREA.IT IS CONCERNED WITH NUMBERS AND QUANTITIES AND THE RELATION BETWEEN THEM.DEMOGRAPHERS USE THE STATISTICAL METHOD IN THEIR ANALYSIS OF DEMOGRAPHIC DATA.

11. DEMOGRAPHIC DATA PROVIDE A BASIS FOR PREDICTING FUTURE TRENDS AND MAKING INFORMED DECISIONS,AS PANOPIO STATES, DEMOGRAPHIC DATA ARE IMPORTANT FOR THE FORMULATION , IMPLEMENTATION, AND EVALUATION OF PLANS, POLIICIES, AND PROGRAMS FOR EDUCATION ,HOUSING,HEALTH, EMPLOYMENT, TRANSPROTATION ,RECREATIONAL NEEDS AND OTHER FORMS OF SOCIAL SERVICES.

13. VITAL REGISTRATION STATISTICS SYSTEM LIKE BIRTH, DEATH, MARRIAGE, AND DIVORCE.

14. SAMPLE OR SPPECIAL SURVEYS LIKE SURVEYS OF HUSEHOLDS

17. SEX COMPOSITION REFERS TO HOW THE TOTAL POPULATION IS COMPOSED IN TERMS OF BEING MALES OR FEMALES.

18. DEPENDENCY RATIO REFERS TO THE PROPORTION OF THE 0-4 AND THE 65-OVER AGE LEVELS PER ONE HUNDRED PERSONS AGED 15-64.WITHIN THE YOUNG AGE STRUCTURE IN THE PHILIPPINES ,OUR DEPENDENCY RATIO IS HIGH COMPARED WITH THE DEPENDENCY IN DEVELOPED COUNTRIES A HIGH DEPENDENCY RATIO IMPLIES HEAVY FINANCIAL SUPPORT FOR MORE DEPENDENCIES.

20. SECOND STAGE-THE BIRTH RATE REMAINS HIGH BUT THE DEATH RATE DECLINES AS THE NUTRITION,HEALTH,AND SANITATION IMPROVE.

21. STAGE THREE-BOTH THE DEATH AND THE BIRTH RATE ARE LOW AND IN BALANCE AGAIN. -
