Template:Poptoday/doc

The Template:Poptoday calculates the estimated daily population, based on parameters for a known base plus daily increment value. The template name "poptoday" can be used as an accessor template with the {Data...} template family, such as with "".

Examples:


 * "" gives ""
 * "" gives ""

The current population, for today, is estimated by extrapolation, using a base population count on a base date, and extrapolating, based on the observed increase per day.

The increase is 30 ppm/day for the world, and for a country usually between 10 and 50 ppm/day. Since the estimate is based on the day, not on the time of day, the precision is at most 10 ppm, so there are at most 6 significant digits in the estimated population count.

Parameters
The following parameters are used by {poptoday}:
 * 2=comma     - put commas in population count (same as: 2=formatnum)
 * 2=formatnum - put commas in population count (same as: 2=comma)
 * popbase     - the base count of the population
 * popinc       - the daily increment of the population
 * popbasemonth - the month of the population base count
 * popbaseday - the day of the population base count
 * popbaseyear - the year of the population base count

Whenever "poptoday" is used as an accessor template, then the parameter values are set inside the host template.
