At world level, the current official number of large camelids cannot be determined exactly (it is estimated to be more than 35 million heads), and the role of camels in the livestock economy is highly variable. The only reliable statistics are provided by FAO since 1961. According to these data, five different patterns of demographic changes have been observed. In countries marked by a regular or drastic decline of their camelid population, a tendency to re-increase has been in force since the beginning of the century, except in India. Generally, countries marked by a sharp recent increase in their large camelid population have implemented a census and readjusted their data. Many inconsistencies occur in available data, most notably cases arising from changes occurring in state status (for example secession of Eritrea, Soviet Union collapse). Moreover, large camelid stocks in Australia, in countries of new camel establishment (Western countries) and those related to the expansion of camel farming, notably in Africa, are not recorded in the international database. In addition, there is no distinction between dromedary and Bactrian data. The present large camelid population in the world is probably more than 40 million and could reach 60 million after 25 years from now if the current demographic trend is maintained.

世界上有多少只大型骆驼科动物？对世界骆驼人口变化的综合分析

在世界范围内，目前尚无法确切确定大型骆驼科动物的官方数量（估计超过3500万头），骆驼在畜牧经济中的作用变化很大。粮农组织自1961年以来提供唯一可靠的统计数据。根据这些数据，观察到五种不同的人口变化模式。自本世纪初以来，在骆驼种群有规律或急剧下降的国家中，除了印度以外，一直有重新增长的趋势。总的来说，最近骆驼种群大量增加的国家已经进行了人口普查并重新调整了数据。现有数据中存在许多不一致之处，最显着的情况是国家地位发生变化（例如，厄立特里亚解体，苏联解体）。此外，国际数据库中未记录澳大利亚，新建立骆驼的国家（西方国家）的大型骆驼科动物种群以及与骆驼养殖业扩大有关的种群，特别是在非洲。另外，单峰骆驼的数据和双峰的数据之间没有区别。如果维持目前的人口趋势，目前世界上大量的骆驼科动物种群可能超过4000万，并且从现在开始的25年后可能会达到6000万。
