This is a documentation subpage for Template:Poptoday. It may contain usage information, categories and other content that is not part of the original template page. |
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}}"
→ "339034000" [1]
"{{data United States|poptoday|formatnum}}
" gives "339,034,000""{{data world|poptoday}}"
→ "8168720000" [2]
"{{data world|poptoday|formatnum}}
" gives "8,168,720,000"
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.
