Conclusion for important types of maps? can you give answer briefly?
Answers
Explanation:
The maps presented in this monograph suggest just a few of the numerous ways that demographers can use contour maps to clearly, efficiently, and simultaneously display both persistent global and prominent local patterns in population rates or levels over two dimensions. In particular, contour maps can strikingly reveal the interaction between age, period, and cohort patterns. By using small multiples, computer movies, or ratio surfaces demographers can use the maps to gain access to several dimensions.
Even in cases where some demographic data already have been carefully scrutinized by perceptive analysts who have uncovered most of the interesting patterns, contour maps may be useful in highlighting these patterns. With contour maps, what was before understood now can be seen. Furthermore, the maps, by giving demographers a new perspective on data, may focus attention on some neglected aspects and patterns in even thoroughly studied data.
