World Birth Death Rate Statistics and What This Truly Signify About the Future of Humankind
Introduction:
The world population has grown tremendously in the last one decade. In 2011 alone, the world population passed a 7 billion mark. Let me take you back a little bit; there was once a time when the population growth rate remained at the zero mark, for years, and it was until the 1,700s that the actual growth rate began.
Growth rate statistics:
For about 50 years, between 1850 and 1900, population growth rate was at the 0.5% mark. By mid-1960, the growth rate had already surged to 2%. But population analysts argue that by mid-1980s, population growth rate declined to 1.7%. By 2005, the population had already declined to almost, about, 1.2%. The population is beyond the 7 billion mark, and the population will reach the 8 billion come 2024.
Population Growth Rate Speed:
The world population doubled in just forty years. From 1959 to 1999, the figure moved from three to six billion. By 2056, the world population will reach a ten billion mark. As it stands, as at now, the population growth change stands at 80 million annually. It is important to note, however, that the worlds population growth rate is declining, and it will continue to decline in the next coming years in the history of humankind.
Reasons for different growth rates:
Population has no constant growth. We therefore use variables when trying to find out the exact cause behind the trends in population and depopulation, globally and in terms of individual countries. Population growth and change is often as a result of three variables: births, death and migrations. A balancing equation is often used to summarize the relationships among the three variables. To analyze the increase or decrease population, the annual census group finds the difference between births and deaths that have occurred within a given period. To find the growth rate by migration, the team finds the difference between people leaving a country and those entering a country within a given period.
It is important to note that the increase in population will account for quick population growth, within a short time. Note, clearly, that, although we factor in migrations to help determine population growth, it doesn't work accurately for global population growth studies; it is best suited when we are analyzing the population growth within countries alone. Birth rates and death rates work best when we are trying to find an estimated population growth of earth.
The Revolution of Population Mortality:
Dont be fooled to believe that population often grows rapidly because of increased birth rates; birth rates don’t even play part most of the time. The only thing you need to remember is that the Industrial Revolution brought about a decrease in death rates, which is why there has been a rapid growth in the human population.
Current Population Evaluation Statistics Results:
-
As long as farming will continue, and transportation continue to improve, there will be more food supply, hence a reduction in death rates often caused by dangers of famine.
-
Public health and standards of living will keep improving, and this will further reduce the number of death rates in the world.
