is indicated by population changes of demographic patterns which are the birth rate, death rate and growth rates as a nation undergoes development from a pre-industrial to an industrialized economic state. Each phase is characterized by a specific relationship between birth rate ( number of live births per one thousand population in an area) and mortality rate (number of annual deaths per one thousand people). The changing of the rates has an essential impact on the total population of a nation. Each

During the early 1950’s following the conclusion of World War I, the population of many major cities throughout the United States began to plummet as middle class Americans sprawled into neighboring suburbs. Despite overall population growth, as evidenced by the generation born at this time coming to be called “Baby Boomers”, city populations declined continuously as seemingly all residents who were economically able to fled cities in large numbers.

The Hawaiian monk seal, or Monachus schauinslandi, was one of the original species to be placed under the Endangered Species Act that was enacted in 1973. As of 2010, the population of the monk seal is approximately 1,100, with an annual decrease of approximately 4.5%. The Hawaiian monk seal is primarily found on the Northwestern Hawaiian Islands that are made up of coral reef atolls, seamounts, banks, and shoals. This is due to the fact that the monk seals primarily forage on the barrier reefs

functional capacity that restricts the execution of tasks or actions in life situations (WHO, 2015). According to the World Population Ageing report (United Nations, 2013), the number of older people over 60 years old will continue growing; is expected to more than double, from 841 million people in 2013 to more than 2 billion in 2050, which represents 21.1% of global population. Older people experience disabilities due to aging such as decreasing of their physical, sensory and cognitive capabilities

resulting in hunting on a massive scale for many decades. There were several other factors contributing to the decline and subsequent extinction of the species, including shrinking of the large breeding populations necessary for preservation of the species and widespread deforestation; which destroyed its habitat. A slow decline between about 1800 and 1870 was followed by a rapid decline between 1870 and 1890. The last confirmed wild bird is thought to have been shot in 1900. The last captive birds

United states and The Netherlands After a brief increase of population, fewer babies were born in the first nine months of 2015. This recent drop in births among young adults could be encountered with the economic downturn.

Although, the Netherlands and the United States population is increasing, the number of births each year are decreasing. Infant

Kayla Norris Biol 105 Dr. Jessy Robbins Critical Thinking: Why the Stellar Sea Lion is Declining The population of the Western stock of Stellar sea lions has been rapidly depleted, according to the Alaskan Fisheries Science Center of the National Marine Mammal Laboratory (Alaska Fisheries Science Center of the National Marine Mammal Laboratory: Marine Mammal Species, 1994). These sea lions have decreased by 85-90% since 1970 (Donnelly, 2003), from over 250,000 to less than 50,000 (Trites & Larkin

factory of sadness, Cleveland, Ohio has recently struggled to retain its population. In its early years, Cleveland, a key city in the Rust Belt, experienced immense growth with the manufacturing boom of the nineteenth and twentieth centuries. As a result, Cleveland’s population peaked at 900,000 residents in 1950; however, as manufacturing subsided across the United States in favor of a technological era, Cleveland’s current population has declined to below 370,000 (“Cleveland”).
