Harmonizing Statistics And Carrying Out Surveys
While some developed nations are racing ahead in information measurement and tracking many factors including infrastructure, access and usage. Many developing nations are struggling to produce even basic indicators. “The number of Internet users in most developing countries is usually based on government guesstimates or vague estimates”, says Vanessa Gray, ITU Telecom Analyst.
When developing nations do conduct surveys, they are finding the number of Internet users has often been vastly underestimated. This is confirmed by recent Internet user surveys emerging from Latin America and the Caribbean. In Jamaica, for example, an Internet user survey pointed to 23 per cent of the population using the Internet, while the penetration rate before the survey was estimated at only five per cent. A similar phenomenon occurred in Peru, with a survey finding twice as many Internet users in the Capital (Lima) alone than had been previously estimated for the entire country. In Mexico, a recent Internet survey also found twice as many users than earlier estimates. These findings suggest that the digital divide may not be as wide in some places as earlier assumed.
While there are few Internet surveys for developing nations, richer nations are over-surveyed with often conflicting results. At least six Internet user surveys have been conducted in Spain, for example, producing figures ranging from over 50 to less than 20 per cent of the population being online. Internet penetration levels compiled by national statistical offices in Europe are, on average, thirteen per cent below those published by market research organizations.

协调统计和开展调查
虽然一些发达国家在信息测量和跟踪包括基础设施、获取和使用在内的许多因素方面走在了前面。许多发展中国家甚至连基本指标都难以编制。国际电信联盟电信分析师瓦内萨·格雷说:“大多数发展中国家的互联网用户数量通常是基于政府的猜测或模糊估计。”
当发展中国家进行调查时,他们发现互联网用户的数量往往被大大低估了。拉丁美洲和加勒比地区最近开展的互联网用户调查证实了这一点。例如,在牙买加,一项互联网用户调查显示,23%的人口使用互联网,而调查前的普及率估计仅为5%。秘鲁也出现了类似的现象,一项调查发现,仅首都利马的互联网用户数量就比以前估计的全国用户数量高出一倍。在墨西哥,最近的一次互联网调查也发现用户数量是以前估计的两倍。这些调查结果表明,在某些地方,数字鸿沟可能并不像以前认为的那么大。
虽然对发展中国家的互联网调查很少,但对富裕国家的调查却过多,结果往往相互矛盾。例如,西班牙至少进行了六次互联网用户调查,得出的上网人数占总人口的比例从50%以上到不足20%不等。欧洲各国统计局编制的互联网普及率平均比市场调研机构公布的数字低13%。
