1. calculate following increases or decreases in population for following countries.

Country A

Births/1000 = 90
Deaths = 36
Immigrants = 20
Emigrants = 10

I calculate this I get 64/1000

Country B

Births/1000 = 75
Deaths = 15
Immigrants = 10
Emigrants = 2

I calculate this I get 68/1000

Country C

Births/1000 = 25
Deaths = 18
Immigrants = 11
Emigrants = 10

I calculate this I get 8/1000

Country D

Births/1000 = 15
Deaths = 14
Immigrants = 8
Emigrants = 6

I calculate this I get 3/1000

2. calculate doubling time of each of following countries

Country E

Births = 110
Deaths = 50
Calculations I get : for natural growh rate/year i get 6%
doubling time i get 11.6 yrs

Country F
Births = 75
Deaths = 32
calculations I get: natural growth reate/yr i get 4.3%
doubling time i get 16.3yrs

Country G

births = 20
deaths = 13
calcualtions: i get .7% for natural growth rate and doubling time be 100 yrs

Country H

births = 90
deaths = 75
calculations: i get 1.5% for natural growth rate, and doubling time be 46.7 yrs.

3. calculate following dependency ratio for following countries

Country I

% children = 21
% adults over 65 = 12
calculations i get for % adults = 67 and dependency load = 33.

Country J

% children = 47
% adults over 65 = 7
calculations i get for % adults = 46
and dependency load = 54

Country K

% children = 19
% adults over 65 = 24
calculations i get for % adults = 57
and dependency load = 43.

Country M
% children = 43
% adults over 65 = 15
calculations i get for % adults = 42 and dependency load = 58

the question i not get is based on population statistics in every grouping countries E - H & I - M, which 2 countries be run into some serious development problem and population problem in future, explain hypothesis 4 each.

ms. sue i say before that country e run into problem because it have large fast growing population in small period so it will need to face development isse for schools, daycares i think. country m run into problems because more children dependent on parents but i need more thing to add in here to make paragraph big.
Answered by Ms. Sue
I checked some of your math and it seems to be correct.

If a country is growing fast, it needs to be sure it has enough jobs, food and water for the people.

Answered by Mohammad
yeah teacher checked math too and he said was correct but i just not get the last question bit part. for the first part the fast growing population count for children? because then they need more things? the country M :

Country M
% children = 43
% adults over 65 = 15
calculations i get for % adults = 42 and dependency load = 58

the dependency load too much, that mean so many children dependent on parents, but what problem that make?
Answered by Mohammad
ms. sue i right?
Answered by Ms. Sue
The problem is that many parents with a lot of children can't afford to feed and clothe and educate them.

Answered by Mohammad
thank you very much ms. sue :) so they basically have no job and don't get good income right?
Answered by Ms. Sue
Right.

Most countries with a high birthrate are very poor.
