Population size

Population composition

Population distribution

What factors affect population size?

fertility (age)

mortality

migration

Population size

Determines overall demand for health services

Population Composition

Describe characteristics or a population based on factors such as age, sex, education, occupation, ethnicity

Population Distribution

influences accesibility to healthcare environmental factors, lifestyle patterns

Urban, rural, suburban distribution

Health Indicators

defined as summary measures that capture relevant information on different attributes and dimensions of health status and performance of a health system

Crude Birth Rate

Ratio between the number of live births and population during given year and total mid-year population for the same period

General Fertility Rate

Represent the number of children that would be born to a woman if shew ere to live to the end of her childbearing years and bear children in accordance with age specific fertility rate

Crude Mortality Rate

rate of mortality in a given population

Infant Mortality Rate

Probability of a child born in a specific year or period dying before 1

Maternal Mortality Rate

Number of maternal deaths in a given period per population of reproductive age

Maternal Mortality

Death of woman while pregnant or within 42 days of termination

Irrespective of the duration and site, from any cause related to or aggravated by the pregnancy

Maternal mortality ratio

women dying from perperal cases, total number of death due to pregnancy

years of potentital lost due to disability or premature death

Utilization Indicators

Track access to healthcare services and preventative measures

Immunization Coverage

Percent of children who received reccomended vaccines

How can Limited Resources affect CHN

Can hinder data collection, analysis and implementation fo healthy intervention

How can Data Quality affect CHN

Incomplete/inaccurate data reporting can limit the usefulness of morbidity indicators

How can limited infrastructure affect CHN

uneven distribution of healthcare facilities and personnel can create data gaps in certain areas

Collaboration

The act of working together with other officials

Capacity Building

Capability of a community to fix their own problems

Community Engagement

Community will participate/use human resources
