For reference, "cr" is an abbreviation for the Indian word crore, which is 10^7, so this is 669 million people.
> It is written as 1,00,00,000 with the local 2,2,3 style of digit group separators (one lakh is equal to one hundred thousand, and is written as 1,00,000).[1]

> In the Indian system, the next powers of ten are called one lakh, ten lakh, one crore, ten crore, one arab (or one hundred crore), and so on; there are new words for every second power of ten (10^(5 + 2n)): lakh (10^5), crore (10^7), arab (10^9), kharab (10^11), etc. In the Western system, the next powers of ten are called one hundred thousand, one million, ten million, one hundred million, one billion (short scale)/one thousand million (long scale), and so on; in the short scale, there are new words for every third power of ten (10^3n): million (10^6), billion (10^9), trillion (10^12), etc.
Surely they mean "in the English system". In German, we have "Milliarde" between "Millionen" and "Billionen", and so on.
In fact, they will end on "-illion" if it's a power of 10^(6n) and on "-illiarde" if it's a power of 10^(6n+3).
Now, indeed, the split is roughly along the line of English (and Russian, Turkics and Arabic) on the short scale side and everyone else, especially Continental European language speakers on the other. It's not a universal rule: Brazil is maybe the largest defector from the Continental European group to the short scale, but Canada reinforces the rule by using both, with the choice being dictated by whether you're speaking English or French.
It's Wikipedia: feel free to click "Edit" and correct/update it.
For international purposes (america) this “long scale” fall out of use, with he “short scale” being recommended in the U.K. since 1974
The best thing I can offer is that the word "billion" and greater should be regarded as cursed, ambiguous, and shouldn't be used any more.
I know a lot of people who didn't get that memo, because I still see the long scale with some regularity.
That said, the short scale is much more common overall.
Vestiges of it pop up from time to time. It's not really something you can Google directly for, but as an indication, literally the second hit on Google for "thousand million" - a term that only exists due to the long scale, and which is obsolete in the short scale - is an article about a Brexit-related bus ad:

Since Russia uses a short-scale system, the word is no longer in use. https://en.wikipedia.org/wiki/Long_and_short_scales
Meta: the title should be changed, in my opinion.
