 ‘Mortality’ and ‘birth rate’ indicators in demography - Definitions and terminology - author Prof. Marta Sugareva, University of Plovdiv ‘Paisii Hilendarski’

The article aims to provide clarification regarding the content of the concepts of ‘mortality’ and ‘fertility’ in relation to various speculative interpretations of demographic data in Bulgaria. The main statistical indicators are outlined, emphasizing that gross mortality and birthrates (per 1 000 population) can be misleading due to the impact on the age structure of the population. In order to avoid incorrect claims, such as ‘mortality in Bulgaria is one of the highest in the world’ the article suggests using the ‘average life expectancy’ and ‘average number of children per woman’ terms (synthetic birth rate coefficient).

The section Statistical surveys and analysis incudes the articles:

 For the analyses of the socio-economic information - author Prof. Ph.D., Svetlana Saikova, Centre for Empirical Social Research at the Institute for the Study of Societies and Knowledge at the Bulgarian Academy of Sciences

The article discusses issues related to the use of available information on socio-economic phenomena and processes. Envisioned are not only the information produced by the NSI, but also that from other sources - mainly the institutional structures of business and government, social networking on the Internet. There are many indications that the opportunities offered by these sources for analyses and assessments of the condition, changes, factor influences and issues in the objects surveyed are significantly larger than actually used. A consequence of this are the missed opportunities to increase the performance of analyses in the area under consideration.

Through the prism of the main objectives and tasks of the analytical work, existing opportunities, ideas and proposals for improving the effectiveness of the analyses are discussed. Special emphasis is placed on generating ideas for innovation. Discussions of problems and ideas are addressed not only to statisticians but also to all those who use statistical methods in their analytical work.

 Cognitive potential of the self-determination coefficient of the statistical analysis - author Associate Professor Dr. Lyubomir Ivanov, Economic Academy ‘D. A. Tsenov’ - Svishtov

The article discusses the possibilities of applying the self-determination coefficient in the process of statistical analysis of dynamics. It outlines how the coefficient is evaluated and how its statistical significance is checked. A total of five strands are available in which the coefficient can be used: As a synthesized indicator of the available regularities in a particular time series; as a potential opportunity to build a linear development model; As a measure of predictability of the time series; As an alternative random order test; As a basis for more accurately assessing the adequacy of built patterns for smoothing the time series. Based on data for three demographic indicators, the application of the coefficient in all five directions is illustrated.

 Main aspects from the remuneration system in the National Statistical Institute and the impact of the legislative changes and Structural reforms on them - author Neli Yarlovska, National Statistical Institute, Sofia

An analysis of the main aspects of the remuneration system in the state administration and in particular of the employees of the NSI Headquarters is made. For this purpose, the influence of both the factors typical of the respective organization, such as the type of organizational culture and structure, as well as the impact of the external environment and the amendments of the statutory regulation regulating the salaries in the state administration, are taken into account.

In order to achieve completeness in the understanding of remuneration management policies, they are traced in the context of administrative reform, with three periods in their development. A perverse moment when determining the salaries in the state administration represents the new payment model introduced on 1.07.2012. This is also the reason why in the empirical part of the article the remuneration of the employees of the NSI Head Office should be examined through the prism of the normative regulation before and after 1.07.2012. The factors that lead to wage increases are: staff optimization policy, structural changes in process management, and rational use of budget resources. The basis for determining the size of the increase is the annual employee assessment.

It could be summed up that the new remuneration system, which is aimed at linking the remuneration of employees with the results achieved, poses serious challenges as well. In order to overcome them, the negative effects need to be taken into account in future changes to the legal framework. The payment mechanisms discussed in the article cannot unambiguously denied or favorited. Like the broken clock, which shows true hours twice a day, each of them has some potential.

The section Information, reviews, consultations presents information about:

 Waste statistics - author Hristina Mironova, National Statistical Institute, Sofia

The National Statistical Institute conducts several surveys from a point of view of the source of waste generation, namely: business waste, agricultural, forestry and fishery waste and a self-study about household waste. Addressed in detail was information on recycling and utilization of household waste as a major element of the circular economy.

 Discharging and treatment of domestic waste waters from households in 2005 and 2015 - author Tsvetoslav Stoev,  National Statistical Institute, Sofia

Water is a main source of life on our planet it is used for drinking and for irrigation of agricultural crops. It is a main raw material and finds application in various economic sectors. After its use as wastewater, it can cause adverse effects. The publication follows the removal and purification of wastewater generated by households because of people's everyday living and physiological needs in 2005 and 2015. Both the share of the population by type of wastewater discharge (related to urban wastewater treatment plants, public sewerage without treatment and own treatment) and the quantities of wastewater discharged by type are reviewed. The data are presented at national and statistical level (NUTS2), a comparison with European countries is also made. Wastewater from industry, services, non-point sources, etc., which also fall into public sewerage, are not considered.
