With the help of given statistical data, prepare a simple bar graph and answer the following questions :Brazil – Urban population in percentage (1960–2010)Years : 1960, 1970, 1980, 1990, 2000, 2010% of urban population : 47.1, 56.8, 66.0, 74.6, 81.5,…

Graph (simple bar graph): Title: Brazil – Urban population in percentage (1960–2010). X-axis: years; Y-axis: percentage of urban population. Scale: Y-axis 1 cm = 10%. Draw six bars of equal width with equal gaps:

Write the title, scale and labels of both axes on the graph.

(Note: a picture of the graph cannot be shown here; in the examination the graph itself must be drawn on graph paper as described above.)

Answers:

(1) The interval of the data is 10 years (one decade).

(2) The decadal increase falls every decade (9.7, 9.2, 8.6, 6.9 and 3.1 percentage points); the decrease in the rate of urbanisation is most marked in the decade 2000–2010, when the increase was only 84.6 − 81.5 = 3.1%.

(3) The increase from 1970 to 1980 was 66.0 − 56.8 = 9.2%.
