1. BASIC CHARACTERISTIC, DISTRICTS
In the long time series, an emphasis is placed on the methodological comparability of data in particular. A number of changes occurred over the whole period, which were brought about by the Czech Statistical Service striving for the international comparability of methods and results of surveys. The organizational structure of the national economy saw changes too. This was why the time series of indicators had to be adjusted to correspond to the methodology and organizational structure of the latst year published (2008) so that a correct assessment could be placed on the long-term development. However, all the value indicators are given at current prices as sufficient relevant data on price developments in both production and consumption areas have not been available in the regional breakdown needed. All the data are converted to correspond to the new territorial self-governing units (new administrative regions). This adjustment was made by redistributing data on whole districts. On 1 January 2007, there was a shift of some municipalities to districts so that the territories of administrative districts of municipalities with extended competence correspond to the territories of districts. The scope of these shifts differs by regions. In some regions no shifts took place, in others the shifts were relatively big. We made an effort to recalculate data in the long time series to the new territorial structure. The recalculation is clearly possible in indicators that are kept down to the level of municipalities. Wherever the data are surveyed in a sample survey and are only estimated for the lower territorial level by mathematical and statistical methods, the recalculation is more difficult and for part of indicators it is not possible at all. Due to the conversions some data are not the same as those published before. In some cases the subject-matter contents differ from data revealed in Chapter 15 – Territorial comparisons and, as the case might be, from data in the other chapters. The reason behind is the efforts to achieve long-term comparability. The time series of regional GDP indicators is fully comparable. The figures on emissions from stationary and mobile polluters (REZZO 1 – 4) are comparable in the time series. Population: the data are comparable in terms of methodology in the whole time series. Until the year 2000 they followed the results of the census as at 3 March 1991, from 2001 they already follow up the definitive results of the Population and Housing Census as at 1 March 2001 on the basis of which demographic balances in this decade are being processed. In accordance with international conventions, the data also include numbers of foreigners staying long in the country. The relative indicators are based on mid-year population figures in respective years and are fully comparable, too. Labour market: Labour Force Sample Survey provides data on labour market on the level of regions; the data are comparable as for time. In statistics of enterprises there were considerable changes in the borderline between large (surveyed) and small (not surveyed) enterprises. These changes concern the trend in the number of employees in particular and, to a lesser extent, the development of the average monthly wage. The set of reporting units concerned developed as follows:
The data are broken by region of the workplace; since 2002, newly included are also small enterprises with less than 20 employees. The classification to industries is governed by the principal activity of the enterprise. Unemployment: the data as for the number and structure of the unemployed are fully comparable. However, the methodology changed in the half of 2004 as for the calculation of registered unemployment rate. Since 2005, this indicator is published only according to the new methodology. Agriculture: a significant change in the methodology occurred in 2002. Classified In agriculture according to standards of the EU are units which exceed specified “threshold limits” such as farming on one hectare of agricultural land or breeding one head of cattle or two pigs or 50 hens, etc. Smaller agricultural activities have been have been classified under the household sector as “hobby activities” of the population. However, their extent at the regional level is impossible to establish with sufficient reliability. Any retroactive conversion of time series to a comparable basis is impossible, either. Industry: only the data referring to years since 1997 are comparable. They refer to enterprises with 100+ employees having their head offices on the territory concerned. Since 1997 industrial activity sales are also monitored, in place of the former production of goods (gross production). In construction, too, fully comparable data are available since 1997 (enterprises with 20+ employees and based on respective territories). On the other hand, the data on housing construction and building permits are comparable in the entire time series rather easily. Education: time series had to be completely restructuted. The system of reporting has been changed. The system of secondary education cannot be clearly broken by individual types of schools any more. In addition, all types of schools now cover pupils who were before independently reported by special schools. The information is taken from the departmental information system of the Ministry of Education, Youth and Sports of the CR. Culture: the data on the number of establishments and facilities are surveyed directly in individual districts, irrespective of the founder. They are fully comparable in the time series. Health: the data are taken from the departmental information system of the Ministry of Health of the CR. The time series is comparable since 2000, when data on the health establishment falling under all ministries are given (before 2000, only health establishments of the Ministry of Health of the CR). Detached units of the health establishments are not covered (unlike Chapter 14). Comparability of time series was broken in 2007 when the number of physicians included also contract workers. Social security: the data source is the departmental survey taken by the Ministry of Labour and Social Affairs of the CR, whose results give a view of social care from the angle of the management structure. In 2007 in relation to the amendment of the act significant changes in the structure (also in names) of individual social care establishments took place. Crime and accidents: included are data from the departmental information system of the Ministry of the Interior of the CR, which are fully comparable in the time series. Older data are difficult to publish as they are not available itemized by district, which is why data for new administrative regions could not be produced. DISTRICTS Evaluating the comparability of data on individual districts is governed by the same principles as those applying to time series for the whole region. The time series can be used virtually without any restriction given the fact that the tables deal with the years 2006 - 2008 it should be considered that some data are recalculated to the new territorial structure in the entire time series and some data cannot be converted (as marked in tables broken by district). * * * Other information is published on the CZSO web pages: /csu/xc/kraj /csu/xc/okresy |
