Demographic Indicators

• Used to eliminate differences based on population size and enable comparisons
• Types: Mean, Median, Ratio, Proportion, Rate, Probability

Arithmetic Mean

• Calculated by dividing the sum of values by the number of observations
• Example data set (25, 30, 42, 27, 15, 13): Mean = 25.33

Median

• The value that divides data into two equal parts
• 50% of observations are above the median.
• Calculation for unclassified data: If odd number, midpoint after sorting. Example (5, 6, 4, 7, 5, 8, 38, 7, 4): Median = 7
• Calculation for unclassified data: If even number, mean of two midpoint values after sorting. Example (65, 75, 72, 50, 34, 59): Median = (59 + 65) / 2 = 62

Median calculation for classified data

• Lo: Lower limit of the age group of the P/2nd person (P/2'nci kişinin içinde bulunduğu yaş grubunun alt sınırı)
• fo: Total population of the age group where P/2nd person is located (P/2'nci kişinin bulunduğu yaş grubunun toplam nüfusu)
• ∑ fo : The sum of the populations of all age groups before the age group in which the P/2nd person is located (P/2'nci kişinin bulunduğu yaş grubundan önceki bütün yaş gruplarının nüfuslarının toplamıdır)
• i: The size of the age group in which the P/2nd person belongs (P/2'nci kişinin içinde bulunduğu yaş grubunun genişliği)
• Formula, O = Lo + Σ foxi / fo

Ratio

• One number divided by another.
• Ratio = x/y (x and y are independent of each other)
• Obtained by dividing two different variables or events within a whole and multiplying by a multiple number (e.g., 100, 1000).

Gender Ratio example

• Ratio of men to women per 100 women
• 336,835 men / 319,582 women * 100 = 105.4

Disease Ratio Example (patients/healthy people)

• Used to compare the number of patients to the healthy population per 100 healthy people

Proportion

• Numerator is fully contained by the denominator
• Proportion = x/(x+y)
• Typically expressed as a percentage

Rate

• Number of events occurring in a given time period divided by the population at risk.
• Formula = e/p
• Denominator isn't just the population
• Shows how many people are at risk and for how long.

Rate Examples

• Crude birth rate
• Crude mortality rate

Rate: Elements

• Duration (minutes, years etc.)
• Event (births in a year)
• A group that will experience the event

Rate and Ratio Difference

• Rate: a / N(a+b) ×k
• Ratio: a /p ×k

Morbidity Rates (Vital Statistics)

• Morbidity (disease) indices
• Fertility indices
• Mortality (death) indices

Prevalence Rate

• Measures the prevalence of diseases in a population.
• Shows percentage of sick people in a population (old or new).

Incidence Rate

• Calculated by dividing the number of new cases by the population at risk.
• Shows how many people are newly infected.

Probability (Demographic)

• Calculated to assess the likelihood of a characteristic in a given population.
• Example: Proportion of the population in a certain age group.

Examples of Demographic Indicators

• Median age
• Median income
• Median age at marriage

TUIK Data

• Turkish Statistical Institute data for population, growth rates, and proportions in different age groups.
• Examples of population pyramids (age distribution)

This quiz covers key concepts in demographic structure and health as taught in NUT 107 at İstanbul Kent University. Topics include demographic indicators, world population trends, and the relationship between population policies and nutrition. It also explores maternal and child health and the impact of sustainable development goals.
