Enrichment Activity: Time analysis
Teacher version

Let's look at how the population changed over time. We can access earlier census data through E-STAT. Then, we can make a comparison between our findings and observe whether there is a trend.

1. Click on Search Censuses on the left sidebar and select an older census (1986, 1991, or 1996).
2. Following the same procedure as before, construct a table, bar chart, and histogram for the percentage population of 10-to-14 age group males and females in the year of your choice.

Analysis:

1. 1986: male: median = 3.87, mean = 4.00 ; female: median = 3.65, mean = 3.76
   1991: male: median = 3.74, mean = 3.80 ; female: median = 3.53, mean = 3.62
   1996: male: median = 3.79, mean = 3.86 ; female: median = 3.64, mean = 3.65
2. The percentage population of the 10-to-14 age group is generally decreasing over time across the provinces/territories.
3. 1986, 1991, 1996: Newfoundland and Labrador
4. Nunavut, as it became a territory in 1999.
5. Nunavut used to be part of Northwest Territories. Nunavut has a very low population; therefore, when part of Northwest Territories, it does not really affect the population distribution of that region. It shifts the Northwest Territories slightly away from the center of the histogram, but Nunavut itself as an outlier disappears.
