They are collected by governments or other organizations for non-statistical reasons to provide overviews on registration, transactions, and record keeping.  They evaluate part of the output of administrating a program. Birth and death records, regulating the crossing of people and goods over borders, pensions, and taxation. These types of data are used in the supply of information. This allows administration data, when to turn into indicators, to show trends over time, and to reflect real world information. The management of this information includes the Internet, software, technology, telecommunications, databases and management systems, system development methods, information systems, etc. Managing the resources of the public sector is a complex routine. It begins with the collection of data, then goes through the hardware and software that stores, manipulates, and transforms the data. Public fonts are then addressed, including organizational policies and procedures. 
The original use of administrative data dates back centuries as often as it was to record land holdings. In the eighteenth century the first offices for the collection of administrative data were founded.  In the nineteenth century international cooperation was established, such as the International Statistical Institute . 
Up until the 1980’s, America’s national unemployment rates were a count of National Insurance cards and local employment offices. Later in the 1980’s, computerized data has been obtained in the form of individual records.

The appeal of administration is cost-effective, and cost-effective.  The government does not provide invasive information to the population. These data are able to record individuals who may not respond  The information that can be valuable, especially when linked. 
Open and linked administrative data
Open administrative data allows transparency, participation, efficiency, and economic innovation.  Linked administrative data permits for the creation of large data sets and has become a vital tool for central and local governments conducting research.  By linking sections of data individually, the online web of administrative data sets are built. For example, open public sector data in Europe.  This 2011 study covered 21 open data projects in 10 countries with marginal cost operations.  The Open Data Ottawa was launched in 2010 in order to engage citizens, create transparency, reduce costs, and promote collaboration with the public. 
Some of the reasons why administration is sought after These data are collected regularly and are collected regularly.
The Justice Data Lab (JDL) established by the Ministry of Justice in the United States of America. The JDL case study explores how smaller organization achieves access to administrative data. The business revealed by actors (VCS organizations, social enterprises, and private businesses), Government departments’ engagement with the users of the volume of output. This paper is intended to develop new data-sets and methodologies to showcase how to open and manage administrative data. However, the cost of production and institutional technology is not free. Concerns about open data and beyond the limits of competition. Examination is mostly focused on creating projects for political and economic gain and implementation, sustainability, user ability, and ingrained politics. 
Some disavatanges of administration data are that the information is not always open and is restricted to certain users.  There is also a lack of control over the content of the data, to increase the efficiency of statistical operations.  These types of data.  Changes in methodology can be obtained in the context of data collection, for example, when using these data to assess health care quality of introductions of new diagnosis and advances in technology can affect the identification and recording of diagnoses on administration claims. Issues with data protection is becoming more open data. = Statistics Canada seeks to reduce the privacy of personal identifiers.  The personal information, such as name, health number, or Social Insurance Number is then stored separately. However, access to linked files with personal identifiers is allowed in these cases with authorization and security, such as encryption, applied.
