LIFE EXPECTACY

LIFE EXPECTANCY
Firtly I want to define what life exectancy is, it is the average period that a person may expect to live. It change depending in the ecomic, social and cultural factors of the country you live in (LEDCs, MEDCs or DCs).

 Longest life expectancy:
In this geographic map that we can see below, are indicated the ten longest life expectancy countries: Japan, Switzerland, Singapore, Australia, Spain, Iceland, Italy, Israel, France and Sweden. As we can see the longest life expectancy countries are always from Developed Countries.


 Shortest life expectancy:
In the opposite side ten shortest life expectancy countries are: Sierra Leone, Angola, Central African Republic, Chad, Ivory Coast, Lesotho, Nigeria, Somalia, Cameroon and Mozambique. Those countries with a short life expentancy belong to LEDCs.

 Some factors that contributed to the longer or shorter life expectancy are:

  1. GENDER: According to the Institute and Faculty of Actuaries, mortality rates for females are lower at each age than those of men. Women live longer than men, on average.
  2. GENETICS: There appears to be a link between genetic factors and mortality rates. Genetics may play a role in nine of the top 10 causes of death, according to the Centers for Disease Control. This is happening  because men work in harder jobs, smooking and alcohol could also be a cause, food safety and motor vehicle safety are some of the reasons of genetics and lifestyle could change life expectancy. 
  3. PRENATAL AND CHILHOOD CONDITIONS: Poor conditions in utero, at birth and in very early childhood are associated with higher mortality even at advanced ages, according to IFA. The Society of Actuaries has been studying the impact of early childhood conditions on exceptional longevity, including whether growing up in a city or farm environment affects longevity, as well as whether growing up in certain geographic areas is associated with differing life expectancies.
  4. MARITAL STATUS: Married people have lower mortality rates than those who were never married, are divorced or are widowed, according to IFA. 
  5. EDUCATION: Higher education levels are linked to higher socio-economic status and both are linked to improved longevity.
  6. MEDICINAL TECHNOLOGY: Advances in medicine and medical technology have had a major impact on increased longevity. Development of antibiotics have helped push the average life expectancy higher.

ANALYSIS OF A POPULATION PYRAMID

Analysis of a population pyramid you can click here to know more information In first place we are going to define what a population pyramid is: it is a graph that shows the structure of a society by sex and age at a given time and place. We can divide this pyramid into three sections: young dependents (0-14), working population(15-64), old dependents (65+). According to the sex structure of this graph, the sex ratio at birth is equaly, the number of girls born are the same as boys (16%), so the sex ratio matches in 0-4 level. In the other hand women have the higher life expectancy. The reasons of that might be historical, dangerous jobs and smoking of men and healthy life of women. With regard to the age structure of the pyramid we can say that it corresponds with the first stage, It has expansive shape and concave sides because of the high birth rate (39.3% 0 ) and the high death rate (14.5% 0 ), consecuenly the net migration is negative and the real increse is lower ...

DECLARATION OF INDEPENDENCE

The American Declaratation of Independence is a document,  approved by the  Continental Congress on July 4, 1776, that announced the separation of North American British colonies from Great Britain. It talks about what they called unalienable rights: equality, liberty and the pursuit of happiness, despite they (upper class) omitted Indians, black slaves and women. I think that both historian,s interpretations of this statement could be close to reality, it is an evidence that Bernard Bailyn one adopts the most extreme position, he says Americans believed an evil and deliberate conspiracy of Britain against their liberty, they believed that England was trying to enslave them and the only option that they had to protect themselves was to use the power which God has given to them. In the other hand Howard Zinn talks about people´s history of the United States, he thinks that the main point of this declaration was the way in which upper class persuade the lower class to jo...

MIGRATION: SPAIN IN-OUT

SPAIN IN                       Firstly I am going to analyze the inmigration in Spain, inmigrats that come to Spain with the dream of get a new life are usually from LEDCs such as Morocco (30%), Romania (25%), Ecuador (10%), Colombia (12%), Peru (5%) or Bolivia (2%). Inmigrant from those countries came to Spain every years to get better conditions, job, home, rights... Luckily most of them found a job, working as agricultors, builder or cleaners and could life better but not the best. Also Spain in this case, get some "exchange" if we can call like that, because they pay taxes, population increase and lot of things that contribute to the country.  In the opposite side the inmigrants that came from MEDCs such as United Kingdom, France or Germany are usuallyyoung people that have studied a career and want to find job; or retired people that like Spain and want to life here to being comfortable.   SPAIN OUT ...
