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}}
- {{data United States|poptoday|formatnum}}
- {{data world|poptoday}}
- {{data world|poptoday|formatnum}}
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
[සංස්කරණය]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.
