3. Note the following for each country:  New Zealand

Males per 100 Females:  100.3

People per square kilometer:  18.4

Number of children per woman:  1.9

Current Population:  4.9M

Estimated Population 2050:  5.9M

Note the following for each country:  Ireland  

Males per 100 Females:  99.8

People per square kilometer:  74.4

Number of children per woman:  1.9

Current Population:  5.1M

Estimated Population 2050:  6.3M

4. Describe and compare the structure of the population pyramids and indicate the stage of the population transition for each. (Hint: Looking at the graph, what does it tell you about the birth rate and death rate over time of the country?)

in New Zealand, the brith rate for the males is 3.3% and for the female it is 3.1%. While in Ireland the birth rate for the males is 3.6% and for the females it is 3.4%.  

Then the population where it is the greatest in New Zealand is the ages 25-29. The males is 3.8% and for the females is 3.6%. While in Ireland, the population where it is greatest is the between the ages 35-39. Both males and females both are at 4.1%.

Then lastly for the ages where the population is less is at the ages 65 and older.

Overall, the graphs tell me that the populations for both countries is that it is greater from birth to their middles ages. Then population decreases when they are 65 and older.  

5.  Finally, how will the two countries compare (to current population) in 2050? How is this reflected in the population pyramids?

If you wish, you can include the population pyramids, but that is NOT a requirement.

The population in 2050 for New Zealand is 5.9M and for Ireland it is 6.3M. That tells me that Ireland will have a greater population in 2050 by 0.4M people. In the graphs, it shows that it is increased from the "Current and Projected Population" graph.
