Graph A:
This stage is characterised by a decline in death rates,[link widoczny dla zalogowanych],[link widoczny dla zalogowanych], although birth
rates remain relatively high, and the boost in birth rates is as a result of
amended sanitation,[link widoczny dla zalogowanych],[link widoczny dla zalogowanych], improved medical care and increased food afford. From the
chart this stage is described by the period 1400 to 1800 where the population
size increases by larger margins deserving to low death rates. (Beaver, 1995)
The chart beneath shows the population size because the year -8000 to 2050,
data was retrieved from the U.S. Census Bureau database:

Stage 1 (-8000 to 1400):
According to the demographic transition theory this stage is
characterised by high birth and necrosis rates, from the chart during this period
the population remained relatively settled and population alterations were
relatively cheap, according to the theory high death rates are as a outcome of
meager sanitation, lack of medicinal care and ailments. High birth rates are also
apparent in this stage and this is for the human ambition to replace the dying
population, they absence children to work and the lack of contraceptives to depress
birth rates. (Beaver, 1995)
According to the demographic transition theory the forth stage is
characterised by birth rates lower than death rate, this levels threaten the
societies today sample Germany where birth rates are relatively lower than
death rates, this leads to a decline in population size, high death rates are
due to lifestyle sicknesses such as obesity and low birth rates are due to increased
contraceptive use and other birth control means. (Beaver, 1995)
The upon blueprint can be subdivided into 4 stages along apt Beaver (1995)
who interprets the demographic transition theory, these stages are argued
below:
Other factors namely explain this changes is war and diseases, from the
chart the period 1900 to 1950 depicts one increase in population size but art a
lower rate than previous years, this can be explained by the subsistence of campaign
in this period, whereby the premier WW 1914 to 1918 demanded 15 million lives, the
Stage 4 (1990 to 2050):
Stage 2 (1400 to 1850):
In stage 2 birth rates were still relatively high but in this stage
improvements in medical care and the presentation of contraceptives lead to a
decline in birth rates, additional factors that affect birth rates is that there is
increased schooling of women, increased status of women in the society and
therefore women are busy in additional activities of economy developed preferably
than child birth, decline in the merit of children whereby in the past people
needed kid to help in harvest activities but at this stage this claim
declines, and finally decline in food supply reduces birth rates. (Beaver,
1995)
Stage 3 (1850 to 1990):
