This page attempts to present a list of languages by total native speakers. Note, however, that lists such as this may vary somewhat depending upon the definition given to certain terms. In particular, the exact difference between "dialect" and "language" is often important.
An example of where this can have an impact is the case of Arabic, which can be considered either a single language or a group of related languages. The World Almanac, the CIA World Factbook, and Ethnologue, the sources of the tables given below, consider the varieties of Arabic to be separate languages. If the spoken varieties listed by Ethnologue are considered as forms of a single Arabic language, it appears in fourth place with about 215 million speakers.
A similar situation occurs with Chinese. If all the varieties of Chinese are counted as a single language, then Chinese appears in first place with over 1.2 billion speakers. If counted separately, then five varieties of Chinese are found in the top 25.
Note that these lists only take into account first-language (native) speakers. Counting second language speakers is extremely difficult and approximate at best.
The following table is based largely on a list of the world's top 100 languages published by Ethnologue in 1999. [1] Many of the estimates are for years prior to 1999. Notes indicate where information in the current table differs from Ethnologue's estimates.
The original Ethnologue list included Serbo-Croatian with 21 million speakers.

Note 1: Ethnologue does not consider Standard Arabic (Fusha) to be a "mother tongue", i.e. a language with native speakers [2]. It counts each of the spoken varieties of Arabic as a separate language. The sum of Ethnologue's estimates of native speakers of all of the spoken varieties of Arabic is about 215 million. The variety with the largest estimate is Egyptian Spoken Arabic with 42.5 million speakers, followed by Algerian Spoken Arabic with 22.4 million speakers.
Note 2:Punjabi is separated into two languages by Ethnologue: Western Punjabi (30,000,000) and Eastern Punjabi (26,013,000). This total is based on new figures in the 15th edition.
Note 3: Ethnologue gives an estimate of 59 million for Turkish.
Note 4: Ethnologue estimates 37 million for Italian. It limits its definition of Italian to the standard language and considers Venetian, Sicilian etc. to be separate languages.
Note 5: Ethnologue splits Persian (Farsi) into two languages: Eastern Farsi (7 million) and Western Farsi (24.28 million).
Note 6:Azerbaijani is split by Ethnologue into North Azerbaijani (about 7 mln. speakers) and South Azerbaijani (about 24.4 mln. speakers).
World Almanac estimates (2005)
The World Almanac2005 estimates for first language speakers are as follows:
The CIA World Factbook provides the following estimates of "first language" speakers for the year 2000 (percentage of world population; CIA's 2000 estimate for world population was 6.081 billion [3]).
