قالب: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 "{{Data United States|poptoday}}".

Examples:

• "{{data United States|poptoday}}" → "344266000" [1]
  "{{data United States|poptoday|formatnum}}" gives "344٬266٬000"
• "{{data world|poptoday}}" → "قالب:Data world" [2]
  "{{data world|poptoday|formatnum}}" gives "قالب:Data world"

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.
