Aim of this agreement
The aim of the agreement is to enable the Statistics Unit to develop and implement a methodology for census‑taking using electronic administrative data held by government departments for the purpose of accurately and regularly measuring Jersey’s population size, characteristics and migration dynamics.
It also ensures such data sharing will be carried out in accordance with the requirements of the Data Protection (Jersey) Law 2005, specifically Schedule 2, paragraphs 5(c) and 6 for the sole purpose of gathering statistical information, which may be used for future policy decision-making.
The Statistics Unit
The Statistics Unit currently produce an Annual Population Estimate report giving total population size and basic migration information each year based on aggregated data from government departments. The Statistics Unit has also run decennial censuses of residents giving full population size and characteristics at a point in time every ten years. A ‘census’ refers to collecting details about every person in a population and is crucial in providing the necessary information for planning, funding and delivering public services (including infrastructure, health, education, housing, benefits, pensions) for that population. Census level data feeds into calculations which project potential future size and structure of the population. The census results are also available to, and highly valued by, commercial and community organisations.
In order to improve the efficiency, quality and timeliness of official population and migration statistics the Statistics Unit is looking to develop and implement a methodology for census taking that uses electronic administrative data already held by government departments.
Responsible persons
The data will only be shared between nominated persons of either party.

Legislative basis
The Census Law (Jersey 1951) allows for the taking of a census. Under Article 2 of the Census Law (Jersey) 1951 the States of Jersey has “Power to make Regulations directing the taking of a census and prescribing procedure in relation thereto”.
Under Section 4.2.1 of P70/2002/ “Machinery of Government: Proposed departmental structure and transitional arrangements”, the Chief Minister’s Department was assigned responsibility for “Jersey’s statistics (including responsibility for the Census)”.
Traditionally in Jersey and other jurisdictions, censuses have been conducted through paper-based questionnaires being completed by every household. The regulation-making powers currently outlined in the Census (Jersey) Law 1951 are specific to this approach – for example the Census (Jersey) Regulations 2010 specified for the 2011 Census the contents of the Census questionnaire form to be completed by householders.
An alternative approach to census-taking, used by 12 European countries for the 2010 round of censuses and being considered for the next UK census, is to make use of government administrative data, held in electronic form, to supplement and potentially replace information obtained through questionnaires. Such an approach has many advantages, including:
- Highly increased cost effectiveness
- Increased frequency of population and migration statistics
- Ability to direct resource to hard-to-capture information to maintain and where possible improve data coverage and quality.
Ministerial Decision (MD-C-2013-0129) approved the forwarding of law drafting instructions to the Law Draftsman for amendment to the Census (Jersey) Law 1951 to allow a defined and limited amount of departmental administrative data to be shared with the Statistics Unit to enable an electronic approach to the population census to be undertaken based on administrative data sources, in addition to the traditional questionnaire-based census approach.
The purpose of this data agreement is to progress work on developing the methodology in advance of the amendments to the census legislation, in order to begin producing improved population and migration statistics.
Compliance with Data Protection legislation
The Statistics Unit will process all personal data in accordance with the Data Protection (Jersey) Law 2005. The data will be used alongside data received from other sources to identify the current resident population of Jersey, and report the characteristics of this population in de-personalised form at an aggregate level in order to inform policy and government resourcing decisions. Article 33 of the Data Protection (Jersey) Law 2005 provides for the further processing of personal data only for research purposes not to be regarded as incompatible with the purposes for which they were obtained.
Given the public function of the Statistics Unit to produce population and migration statistics which underpin government administration planning and funding decisions (thereby being in the public interest), and that the rights and freedoms or legitimate interests of the data subjects are not prejudiced, the processing of information within the limits of this data sharing agreement will comply under paragraph 5 of Schedule 2 of the Data Protection (Jersey) Law 2005.
The purpose of such data sharing is for research and statistical purposes as described under Article 33 of the Data Protection (Jersey) Law 2005. Specifically, the personal data will not be processed to support measures or decisions with respect to particular individuals. Any issues highlighted through data processing to do with data quality (coverage and/or accuracy) of the original data source at an individual (record) level, or individual or business compliance with legislation will not be fed back to the original data controllers by the Statistics Unit.
No sensitive personal data, as defined in the Data Protection (Jersey) Law 2005, will be processed as part of this agreement.
Security and retention of data
Personal data will not be processed (including disclosed) for any purposes other than those stated in this agreement or where the legislation permits and appropriate legal advice has been sought. Only authorised personnel from the Statistics Unit will have access to the data where it is required to fulfil their function.
Under the Fifth Principle of the Data Protection (Jersey) Law 2005, personal data will not be kept any longer than necessary. The Statistics Unit will retain only such data as is required to produce statistical information on the population.
Transfer of Data
Data will be transferred quarterly to a secure file location set up by Social Security and accessible only to authorised persons in the Statistics Unit.
Access of data
The Social Security Department remains the original data controller for the data. The Statistics Unit will redirect any individual’s request for information to Social Security. For the purposes of Article 7 of the Data Protection (Jersey) Law 2005, Article 33 will apply.
Information to be shared
The information to be shared will be limited to the minimum needed to identify Jersey residents and basic demographic characteristics of that population including age, gender, employment status, marital status, place of birth, nationality, length of residency and residential status.
Specific data to be provided by the Social Security department (and reasons associated with each field):
- JY number (as the primary key)
- First and Last names (to assist with duplicate detection, identifying data coverage and quality issues)
- Date of birth (to provide population structure by age)
- Gender (to provide population structure by gender)
- Current address (to identify resident/non-resident records to report migration dynamics)
- Date of most recent arrival (to assist with reporting population structure by length of residency)
- Place of birth (to assist with reporting population structure by place of birth)[1]
- Nationality (to assist with reporting population structure by nationality)
- Class 1 Contributions paid in specified quarter (yes / no flag – to assist with reporting employ status of population, and as evidence of residency for individuals in previous quarter)
- Class 2 Contribution paid in specified quarter (yes / no flag – to assist with reporting employ status of population, and as evidence of residency for individuals in previous quarter)
- Any income support or long term care payment received in specified quarter (yes/no flag, no details of type of benefit needed – as evidence of residency in previous quarter)
- Pension or benefit received in specified quarter (yes / no flag – providing supporting evidence of activity in previous quarter)
- Registration card request made in specified quarter (evidence of residency in previous quarter)1
- Residential status at end of specified quarter (to assist with reporting population structure by residential status)1
- Date of death (to identify deaths)
- Date of exit (to identify those who inform Soc Sec of leaving island and assist with reporting on migration dynamics)
