Question

Choropleth maps are used to represent variables such as the density of population, literacy rates, and sex ratio. How can we classify data to create a choropleth map?

• A. Manually
• B. Non-sequentially
• C. Equal intervals and quintiles
• D. Natural breaks

Answer 1

Answer: (A), (C), (D)

Natural breaks

There is no single best way to classify data into ranges to create classed choropleth maps. The aim of classifying data is to put places with similar rates in the same class and separate places with very different rates into different classes. Each method of classifying data produces a unique choropleth map. The data of the variable is collected by conducting surveys or by other means of measurements. The different ways to classify data are:- quintiles, equal intervals, manually, and through natural breaks. Classifying data into more classes leads to a lesser degree of data generalisation.
