@NOTES AND DEFINITIONS
There have been some significant changes in this edition. The country name Western Samoa has been changed to Samoa. The spelling of Kazakhstan includes the letter "h" once again; the spelling Kazakstan is no longer used. Introduction is a category with two entries-Current issues and Historical perspective-that appears in only a few country profiles at this time. In the future, this category may be added to more countries.
Abbreviations: This information is included in Appendix A: Abbreviations, which includes all abbreviations and acronyms used in the Factbook, with their expansions.
Administrative divisions: This entry generally gives the numbers, designatory terms, and first-order administrative divisions as approved by the US Board on Geographic Names (BGN). Changes that have been reported but not yet acted on by BGN are noted.
Age structure: This entry provides the distribution of the population according to age. Information is included by sex and age group (0-14 years, 15-64 years, 65 years and over). The age structure of a population will affect a country's investment pattern. Countries with young populations (high percentage under age 15) need to invest more in schools, while countries with older populations (high percentage ages 65 and over) need to invest more in the health sector. The age structure can also be used to help predict potential political issues. For example, the rapid growth of a young adult population unable to find employment can lead to unrest.
Agriculture-products: This entry is a rank ordering of major crops and products starting with the most important.
Airports: This entry gives the total number of airports. The runway(s) may be paved (concrete or asphalt surfaces) or unpaved (grass, dirt, sand, or gravel surfaces), but must be usable. Not all airports have facilities for refueling, maintenance, or air traffic control.
