Statistics & Surveys conducted by SDAS

National Accounts Statistics

The National Accounts Statistics is to provide data about the level of economy for use by government, private and overseas analyst, etc., and other economic analyses. The national accounts provide an estimate of the national income which is a measure of the money values of goods and services becoming available to the nation from economic activities thus providing an indicator to monitor the rate at which the country's National Income is growing, etc., and a comparison of the standard of living of different countries.


The national accounts component produces a range of statistics which summarises, in a systematic and comprehensive way, the economic transactions that take place in the Seychellois economy and between Seychelles and the rest of the world. The usefulness of the accounts derives largely from the way in which data are brought together from all available sources and presented in a conceptually consistent way both for a given period  and over time. The accounts basically accord with the recommendations contained in the United Nation's System of National Accounts.


It presents an up-to-date picture of the national economy, summary national income and expenditure accounts at both current and constant prices and provide details of concepts, sources and methods used to compile the National accounts by all users.


Provides a framework for confronting and reconciling data from various sources in order to improve the quality of those data sources by identifying possible deficiencies and inconsistencies.


Employment/ Labour Statistics

The SDAS has so far been able to monitor only formal employment and earning in all sectors. Nothing much has yet been done for the informal sector, for which information is rather difficult to collect.


The purpose is to provide a benchmark on the status of employment and earnings and to provide the government with information as a basis upon which to plan future development and decision-making.


In order to facilitate the collection of data in the public and Parastatal sectors, questionnaires are sent to the Ministries and Parastatal, and they are duly completed on a monthly basis. The required information relates to:

- Number of employees

- Total basic wages/salaries (gross)

- Other payments (e.g. allowances, overtimes)

- Total earnings


All the above information is distinguished between wage earners (temporary persons) and salaried staff.


Information for the private sector is obtained from the Social Security records. The data are collected on a monthly basis and relates to:

- Total earnings

- Total employees


All information is categorised by sector and industry for employment and earnings.


Tourism Statistics

Tourism has become not only a major force in the world trade, but also a vital factor in the Seychelles' domestic, economic, cultural and social development. SDAS provides important statistical indicators in an effort to guide planners with respect to the performance of the industry.


Airport Survey

Three sample surveys are conducted at four monthly intervals on departing visitors in a year. All families are given a questionnaire to complete (with coverage in English, French, Italian an German).


These surveys are the only sources of information that combines the length of stay of visitors with their country/region of residence. Details of their expenditure in Seychelles are requested and the overall expenditure estimates are derived by using these figures in conjunction with information collected from hotels, guest houses etc. Other indicators that are collected include details on multi-centre holidays, repeat visits, level of enjoyment etc.


The results of the expenditure information provide an indicator/check on the foreign exchange earnings from the Tourism Sector collected by the Central Bank.


Tourism Research

Conducts research by interviewing departing visitors.


Demography Statistics

The demography component produces regular statistics on births, deaths, marriages, migration etc. Provide regular statistics relating to the composition, distribution and structure of the population, population projection, survival analysis (expectation of life etc.).


Production Indicators/ Industrial Statistics

The trade component provides detailed statistics on the composition of Seychelles' export and import trade and on shipping and air cargo movements. the component also maintains the statistical classifications for use by importers and exporters in completing customs documentation.


Price Statistics

The prices component of the SDAS undertakes the compilation of the Retail Price Index (RPI). The RPI measures the change each quarter in the cost of purchasing a constant basket of consumers' goods and services. The Retail Price Index, also known to many as the Cost of Living Index measures the change in the cost of a fixed basket of goods. In Seychelles, we have categorised two baskets of goods, one for the low income family (household) and other for the average income family. This basket will be different for each of these families as their consumption patterns are different. The RPI is a measurement of inflation and measures only changes in the cost of living. It does not measure the actual or absolute cost of living (i.e. in monetary terms). For example; a country having a high rate of inflation does not necessarily have a high cost of living.


Household Income & Expenditure Surveys

The 1991/92 Household Income & Expenditure Survey (HES) which derives weights for the cost of living was launched in February 1991 on Mahé, Praslin and La Digue and covered a twelve-month period.


The aims of the 1991/92 HES were to provide accurate and comprehensive information on the components of the average household budget in Seychelles so that a new "consumer price index" could be worked out. The index was based on a budget inquiry conducted on 1983/84 and getting out of date. Secondly, the results were also to provide information on the consumer expenditures and its components that are useful elements in the compilation of the Gross Domestic Product (GDP) and the National Accounts Statistics. A third important purpose is to provide information on the level and distribution of household incomes in Seychelles that is important for social and economic planning. Moreover, the survey provided useful and interesting information to the public concerning the expenditure pattern of households in the Seychelles.


Population Census

The population census and survey unit develops and conducts censuses of population and housing. The purpose of the census is to obtain statistical data, necessary for policy-making and planning at the national and district level, on the demographic, economic and social structures of the population and households.
