Text Solution

Verified by Experts

Figure A It is a 'pyramid' shaped age pyramid. In this figure, the base, i.e., pre-reproductive stage is very large as compared with the reproductive and post-reproductive stages of the population. This type of age structure indicate that the population would increase repidly.
Figure B It is an 'inverted bell' shaped pyramid. In this figure, the pre-reproductive and reproductive stages are same. This type of age structure indicates that the population is stable.
Figure C It is 'urn' shaped pyramid. In this figure, the pre-reproductive and reproductive stages are less than the post-reproductives stages of this population. In this population more older people are present. This type of age structure indicates that the population definitely is declining.
