Environmental Data Explorer Socioeconomic Data and Applications Center DDC Home UNEP Knowledge Repository Internet Data Mining Total Sites Across All Domains (logarithmic scale) Netcraft has explored the internet since 1995 and is a respected authority on the market share of web servers, operating systems, hosting providers, ISPs, encrypted transactions, electronic commerce, scripting languages and content technologies on the internet. By surveying the web, collecting and collating as many hostnames providing an HTTP service as we can find, and systematically polling each one with an HTTP request for the server name, we are able to create datasets that give a clear picture of what is happening on the internet. Customers include: British Telecom, Cisco, cPanel, Datapipe, DigitalOcean, GoDaddy, Host Europe, Intel, Iomart, Microsoft, OVH, Parallels, Peer1, Rackspace, IBM/Softlayer, Symantec, United Internet and a range of investment and venture capital organisations.
Big Data for Sustainable Development | United Nations Big Data The volume of data in the world is increasing exponentially. By some estimates, 90 per cent of the data in the world has been created in the last two years, and it is projected to increase by 40 per cent annually. A large share of this output is “data exhaust,” or passively collected data deriving from everyday interactions with digital products or services, including mobile phones, credit cards, and social media. This deluge of digital data is known as big data. The Data Revolution The data revolution -- which encompasses the open data movement, the rise of crowdsourcing, new ICTs for data collection, and the explosion in the availability of big data, together with the emergence of artificial intelligence and the Internet of Things -- is already transforming society. Opportunities Data is the lifeblood of decision-making and the raw material for accountability. Risks There is also a risk of growing inequality and bias. Big Data for Development and Humanitarian Action Resources
UNSD Environmental indicators UNSD Environmental Indicators disseminate global environment statistics on ten indicator themes compiled from a wide range of data sources. The themes and indicator tables were selected based on the current demands for international environmental statistics and the availability of internationally comparable data. Indicator tables, charts and maps with relatively good quality and coverage across countries, as well as links to other international sources, are provided under each theme. Statistics on Water and Waste are based on official statistics supplied by national statistical offices and/or ministries of environment (or equivalent institutions) in response to the biennial UNSD/UNEP Questionnaire on Environment Statistics, complemented with comparable statistics from OECD and Eurostat, and water resources data from FAO Aquastat. Environment statistics is still in an early stage of development in many countries, and data are often sparse.
