NTA Lab
NTA Lab is an app used to construct graphs and tables using NTA data and AI methods. The user uploads NTA per capita age profiles and optionally population estimates, a consumer price index, and population projections. The most recent version of the app is here:
A master database has been constructed that contains data from the NTA database, and additional data from the US, Japan, South Korea, Colombia. The files provided here can be used in NTA lab.
The NTA master database, with its link below, contains detailed information about constructing the master database. It is used if additional data NTA data are added to the database.
Population projection files based on UN World Population Prospects have been downloaded and are contained here.
The compact file contains projections at five-year intervals. This is best for comparative analysis:
Annual projections are contained in this file. It is too large to be used with the app, but it could be used for a single country or a subset of countries:
Population projection annual series
Population estimates are available here:
And documentation of the construction of these files are here:

The files provided above incorporate some important changes from earlier versions. The NTA Lab app has a new feature that allows the code for any figure to be saved. This makes it possible to replicate figures generated previously. It will then be possible to make revisions to the figure, such as, changing the country, the variable, etc.
In addition, the program for creating the population master file had a bug that has been corrected. Note that the population files for the Philippines (1990 and 1995) contain an error found in the NTA database. This is being tracked down and will be corrected.
A section for selected specialized figures has been added. Included are arrow diagrams, triangle graphs, birth cohort plots, etc.
NTA Lab Manual provides some detailed information about the app.
