Like Nastya Subscribers vs Every Country's Population
Social Blade and YouTube channel pages archived by the Internet Archive for subscribers; UN World Population Prospects 2024 via Our World in Data for population (estimates to 2023, medium projection after), with official national estimates for 18 countries including the United States, China, Japan, Brazil, Germany and Vietnam. Populations are drawn between annual figures, and YouTube has shown subscriber counts rounded to three significant figures since September 2019, so the counters are interpolated between monthly observations. Because of that rounding the channel seems to trade places with DR Congo several times in 2023, although it actually passed it once, around February 2023, and it may already be ahead of Mexico while its rounded count still reads 133 million.

The World's Richest Person Every Year, Rockefeller to Musk (1900–2026)
Forbes, The World's Billionaires (1988–2026); Forbes' first international list (1987 — published as bands such as "over $5 billion", used here as lower bounds, plus the two figures Forbes gave in prose); the Forbes 400 (1982–1989 — the 1985, 1986 and 1987 tables as the Los Angeles Times reprinted them in full, the earlier years from UPI and New York Times reports); Forbes' first rich list (30 Americans, 1918); Fortune's surveys (69 Americans in 1957 and 66 in 1968); Fortune's world billionaires lists (1987–1993); Forbes' rankings of royals and rulers (1999 and 2002–2011); appraised valuations wherever one survives (probate and estate-tax records in England and several US states; a French inventaire après décès; Japan's 1946 capital-levy assessment of personal net worth) and documented estimates where none does (TIME, the Guinness Book of Records' "richest men" entries, a 1961 US State Department memorandum, Rudolf Martin's yearbooks of German millionaires (1911–1914), and period accounts) — the years before 1982 are interpolated between those. Forbes excluded royals and heads of state from its billionaires ranking "because their wealth derives more from political heritage than from economic effort"; Fortune included them. Sovereign fortunes are included here throughout, taken from whichever of the two published a figure. Where a published list exists for a year, no reconstructed value is allowed to exceed it. Some fortunes are counted as families, the way the sources count them; family fortunes that no source ever stated for one person (the Rothschilds, the Guggenheims) are not drawn as a single bar. Portraits: Wikimedia Commons, Wikipedia, Forbes profiles, TIME covers, newspaper archives, and the subjects' own foundations and institutions.

KIMPRO Subscribers vs Every Country's Population
YouTube channel pages archived by the Internet Archive and Social Blade's daily tables, rankings and charts (also archived) for subscribers; UN World Population Prospects 2024 via Our World in Data for population (estimates to 2023, medium projection after), with official national estimates for 18 countries including Japan, Germany, the United Kingdom, Canada, Australia and Vietnam. Populations are drawn between annual figures, and YouTube shows subscriber counts rounded to three significant figures, so the counter is interpolated between observations. Each step is one month, at the observation nearest the month's end; the video starts at zero at the end of July 2022, before the channel's first upload on August 1 (it had no public videos until then).

Populations are drawn between annual figures, and YouTube has shown subscriber counts rounded down to three significant figures since September 2019, so the counters are interpolated between monthly observations. Counts before August 2018 are sums of Social Blade's monthly gains, and the counter runs straight between the few earlier records.

Top 10 YouTubers Combined vs Every Country's Population
Social Blade and YouTube pages archived by the Internet Archive and Common Crawl for subscribers; UN World Population Prospects 2024 via Our World in Data for population (estimates to 2023, medium projection after), with official national estimates for 18 countries including the United States, China, Japan, Germany, the United Kingdom and Turkey. The total counts subscriptions, not people, since one person can subscribe to several of these channels, and channels made by YouTube itself, such as Music and YouTube Movies, are left out as in Wikipedia's list of the most-subscribed channels. Each channel is counted from zero on the day it was created (KIMPRO from the end of July 2022, before its first upload) or from its earliest archived count, and YouTube has shown subscriber counts rounded down to three significant figures since September 2019, so the counters run straight between those observations. The ten channels racing each other on the right are, in their September 2026 order, MrBeast, T-Series, Cocomelon, SET India, Vlad and Niki, Stokes Twins, Kids Diana Show, KIMPRO, Like Nastya and Zee Music Company. The same ten are followed all the way back, so this is not the top 10 of each year.

YouTube channel pages, search results, watch pages and embedded players archived by the Internet Archive Wayback Machine, plus YouTube channel search results on September 29, 2026; Social Blade; Wikidata; SPEAKRJ; Alien Art; Youtubers.me; Whatstat. Each month uses the observation closest to its end. YouTube shows subscriber counts rounded to three significant figures, so the bars and the full-digit counters move in a straight line between monthly observations. The combined total adds up subscriptions, not people, so a viewer subscribed to two channels counts twice. Russian and Hindi channel names are shown in Latin script (MrBeast На Русском, MrBeast हिन्दी).
