This release of the IDB contains revised estimates and projections for 35 countries. For general information about how these estimates and projections are made, see Population Estimates and Projections Methodology.
A substantial change was made for estimates and projections of France. Previously, the French territories of French Guiana, Guadeloupe, Martinique, and Reunion had been treated as separate areas. The France estimates and projections now include these 4 overseas departments as part of the national total. As a result of this change, the number of countries and areas covered by the IDB has changed from 228 to 224. In addition, these areas will now be included in the same regions as France and not in the regions where they were included in prior releases.
1. Expansion of the estimates and projections to age 100+:
In order to better project countries with increasing numbers of people in the oldest ages, we are in the process of converting our projections to be done by single years of age up to 100 years and over. This change was done for the following 14 countries:
The inclusion of new data was done for the following 13 countries:
2. Revised projections for 8 countries with HIV/AIDS using new methodology and procedures:

See Population Estimates and Projections Incorporating AIDS.
Currently, only the "With AIDS" series is shown in the IDB.
The 8 revised countries are:
