If you like my website, and/or if you've found it useful, please consider making a small donation to my Just Giving page, which I've set up just for this purpose. To begin with I'm collecting for a charity whose work I have benefitted from myself (and continue to do so): the British Heart Foundation. It would be great to raise £100 in the first month.

If you have already donated ... Thank You!

World Population

Timeline

The following figures were taken from Worldometers, in May 2017. Since 1951 they have been compiled by the United Nations. They are all, of course, estimates.

According to Worldometer, in 2017 there were about 384,000 births and 155,000 deaths each day – giving a population growth of approximately 129,000 per day, or approximately 1.5 every second. The population of China was estimated to be increasing by approximately one every six seconds, and that of India by approximately one every two seconds.

Annual population growth peaked at 2.10% in 1968, since when it has declined steadily to 1.11%.

The world's 10 least populous countries

Taking our cue from Pointless, these are the least populous member states of the United Nations (UN).

Note that the Vatican City is excluded because it isn't a full voting member of the UN. It is the world's smallest country (sovereign or otherwise), by both population and area. The Holy See, which holds sovereignty over the Vatican, is a full member of the UN but does not have voting rights. (The Holy See is the ecclesiastical jurisdiction – effectively the governing body – of the Catholic Church.)
