Causes of population increase include quality health care, increased food production, immigration, fight against poverty and lack of family planning. High population increase has negative impacts to the country, including conflicts, environmental degradation, high cost of living and reduction in natural resources. One benefit associated with an increase in population is the growth of human workforce.Know More
Improved health care has reduced mortality rates by diagnosing health problems in a timely manner. Use of vaccines has helped to prevent illnesses that used to kill many people in the past. As a result, this has helped save the lives of many people.
Introduction of better farming techniques has boosted the production of food. Also, efforts toward food security have been successful in many countries. Areas where people die as a result of drought and famine get enough food supply thus saving lives.
Increase in the fight against poverty has also contributed to population increase. In the past, only a few families had enough money to support themselves while many families faced many problems, including health issues as a result of poverty. Today, the fight against poverty has helped in a number of ways.
Immigration has also contributed in population growth in developed countries and urban centers. Many people immigrate to other countries in search for better living standards. This has led to an increase of population in many developed countries.
Poor family planning in many families is one of the major contributors to population growth. Many families tend to have many children more than they can support.Learn more about Population & Demography
Hardy-Weinberg problems look at the dominant and recessive traits of a population and determine the percentage of homozygous dominant, homozygous recessive and heterozygous individuals in the population. The Hardy-Weinberg equation is a mathematical expression that is utilized to calculate the genetic variation in a large population. The equation can only be used when a population is in Hardy-Weinberg equilibrium.Full Answer >
The finite population correction (FPC) factor is used to adjust the standard error of a sample mean when sampling is done without replacement and the sample size is at least 5 percent of the population. The FPC factor always has a value of less than one.Full Answer >
An aging population refers to a phenomenon in which the median age of the population in a region or country rises significantly when compared to the total population. This is caused by a declining birth rate or rising life expectancy.Full Answer >
The mortality rate is calculated by taking all the deaths that occurred during a particular time period and dividing that number by the total size of the population during the same time frame. The resulting decimal is then multiplied by 1,000 or 100,000 to give a whole number.Full Answer >
