Picking at outliers

In our last chart, we examined the variation in GDP per person (USD) vs. the population growth %. We will look further at a couple of outliers in this data:
  • Which country has > $10k GDP per capita and a growth rate > 3% ?
  • Which country has approximately 0% growth rate with $1k GDP/person ?
The answers to these two questions can't easily be found directly from the CIAWF data as we're looking at the calculated column (GDP per person) and need to cross-reference with the population growth. However, it is easy to find the answers in BIRT.


We can create a table on the report with Country, GDP/pop (USD) and Pop. Growth (%) columns. Specifying that this table is sorted by GDP / person should make it easy to find the answers.


Extracting data for GDP/person of $40k-$60k, we find:
Country
GDP / person
Pop. Growth (%)
Netherlands
40179.24
0.37
Austria
40402.66
0.03
Australia
40538.97
1.15
Guernsey
42140.53
0.44
Switzerland
42474.04
0.21
Cayman Islands
43787.95
2.29
Gibraltar
44032.32
0.27
Hong Kong
45742.31
0.45
United States
46802.36
0.96
United Arab Emirates
47934.77
3.28
Brunei
50710.39
1.71
Kuwait
52588.43
1.99
Jersey
54162.55
0.84
Norway
54413.52
0.33



So, it appears that the country with a high GDP per person and a high population growth rate is the United Arab Emirates. Similarly, looking at GDP / person of ca. $1000, we find that Tokelau has population growth of -0.1%.
