World socio-economic developments lead to decline the population growth and to increase the life expectancy. When this process is along with fertility decline, it reshapes the age structure of the population and shifts the relative weight from younger to older age groups. Hence, population ageing is a by product of "demographic transition" in which mortality and then fertility decline from higher to lower level. Under the UN classification, persons 60 years old or above called aged. At the present in the world for each individual aged 60 and over, 10 individuals are living. Ageing index has increased from 24 in 1950 to 33 in 2000 and is expected to reach to 101 in 2050.The aged persons in Iran increased from 1.6 million in 1966 to 5.1 in 2006 with an average growth rate of 2.7 percent, which is 1.7 fold of population growth rate in the same period. Ageing index in Iran increased from 17 in 1996 to around 29 in 2006. Considering the other related indices of the aged peoples in Iran, while planning the development program, suitably we have to mainstreaming the needs of older persons and this should be done under the recommendations of the world international assemblies on ageing.

Statistics and information are the basic requirements of scientific development in any domain. To have an accurate image of leisure and cultural domain, statistics and information, which are up-to-date and adapted to each countries realities, are also needed. Observing the standards of producing the statistics in cultural domain provides conditions that by virtue of them, one can draw up the macro-planning and micro-planning of society in the domain of art and culture more precisely and more accurately. It is done by using a general classification of activities, products and cultural occupations as a framework of gathering information and statistics. The existence of such an integrated classification results in promotion of integration of statistical information and deceasing of duplication and parallel activities. By establishment of the SCI and according to part? ?? of article 3 of the low of SCI, this center is responsible for preparing of definitions, assigning the concepts, criterion and statistical classification and according to article 8 of the same law, all of the executive organizations are obliged to obey them. This article is presented with the aim of executing the relevant laws. According to compiling Iran culture and leisure classification, it also examines the definitions, concepts and comparative studies, and finally draws up the classification in 3 distinct parts as cultural activities, cultural products and cultural occupations.

Pervasive development of various sections and areas is an important factor in creation of sustainable development. On the other hand, one of necessary conditions for pervasive development is the fairly distribution of possessions. In this paper we rank the cities of the Khorasan Province (North –South and Razavi) according to the size of development with there methods, Taksonomi, AHP and Principle components analysis and compare them.

Stratified sampling design is used in many different sampling surveys. The method which has being used since many years for stratifying frame members is Dalenius-Hodges stratification method which strongly depends on the distribution of data. This paper contains a study of the former method and Fuzzy clustering method as a method that does not impose any constraint on the distribution of data. Moreover, a comparison between these two methods is considered.As a result, the conclusions of the study shows that in skewed data Fuzzy clustering method is more efficient than the Dalenius-Hodges Stratification method for skewed data and it can be used in surveys at Statistical Center of Iran (SCI).

This paper reviews the most popular methods of calculation poverty line (such as Cost- of-Basic-Needs method, Food Energy Intake method, Subjective poverty line…) and poverty indices (such as poverty ratio, poverty gap index and Sen index). According to international recommendations, poverty line and poverty indices has been calculated for urban and rural areas based on 2300 calorie approach by using household income and expenditure survey's data for the period of 1996 to 2006. In addition, 95% interval confidence was calculated for poverty rate based on boot-strap method.Results show that the share of the poor people decreased from %14.1 to %12.6, and %22.6 to 11.4%. in urban and rural area during the period 1996-2006 respectivly.

Rotation survey is a kind of repeated surveys which can be used not only for the trend study of parameter changes over the time, but also for making improved estimates for a given time interval when the parameter under investigation changes during the time interval. It is time and cost consuming to make use of rotation surveys especially when the time intervals are short, say monthly surveys. Therefore, it is constructive for rotation surveys to take advantage of techniques to decrease sample sizes. In this paper, authors try to represent a way to decrease the sample size required in rotation sampling by using small area estimation (SAE) method. Based on a simulation study, this strategy is compared with traditional method which does not use SAE method.

The UK office for National Statistics (ONS) is responsible for producing a wide range of inflation measures. These include the Retail Prices Index (RPI) and the UK Harmonised Index of Consumer Prices (HICP) which is used for comparisons across the European: union:One of the key components of national statistics is a public commitment to the regular quality assurance of outputs to ensure the professional quality of output. In this context ISO 9000 has become an integral part of ongoing programme designed to improve and maintain the quality of the RPI and HICP. It is now a key element underlying a formal quality management system ISO 9000.The article reviews the meaning of quality in the context of statistical outputs, the different approaches available to quality management and the potential these have to improve performance and how the latter can be measured. It describes some of the benefits that have accrued form using a formal system of quality management and takes a critical look at the lessons learnt.ISO 9000 has been to refer to the series of International Standards Organisation (ISO) Standards, expect references to specific standards such as ISO 9002 or ISO 9001 (2000) apply.
