Exploring solutions for linking Big Data in Official Statistics

Official statistics has acknowledged the value of big data and has started exploring the use of diverse sources in several domains. Sometimes, big data objects can be easily connected to statistical units. If a unit identifier is available, the opportunity to link big data to existing statistical micro data can allow enlarging the content, the coverage, the accuracy and the timeliness of official statistics, for example Internet-scraped data could be used with this aim. In this setting, new challenges arise in data integration with respect to linking administrative data. In this work, we describe a real case of integration of web scraped data and a statistical register of agritourisms specifying the novelties and challenges of the procedure

From east to west: the former USSR citizens in Italy

In the first decade of 21st century the presence of former USSR citizens in Italy has rapidly grown. At the beginning of 2000, according to the data provided by the archive of residence permits, they were less than 24.000 (13.000 Russians). The 2002 regularization programme has had a strong effect in the growth of their regular presence. At the beginning of 2009 they were almost 240,000 (more than 144,000 Ukrainians). They have peculiar characteristics and show particular socio-economic behaviours. A large part of this presence is constituted by women, in many cases middle aged, mostly employed in the sector of family services. In Italy Moldavians, Ukrainians and Russians are the three most numerous communities coming from this area. Our analysis is focused on these citizenships. In the first part of the paper we enlighten the most relevant demographic trends. We discuss the principal changes interested the three communities describing the specific characteristics (gender and age composition, territorial distribution, marital status, reason of the stay, etc.) and demographic behaviours (marriages, births, etc.). In a second part we study, through a longitudinal approach, the changes that have affected the cohort of regularized belonging to the three citizenships. We can distinguish two principle groups: regularized people that continue to have a residence permit in the years following the regularization and regularized people for whom is not possible to find a correspondence in the archives of residence permits. The principal differences between the two groups will be analyzed. For the first group we especially study the changes occurred during the period of observation: particular attention is paid to the internal mobility (and to marital status changes)

Deliverable 2.3 - Research needs in terms of statistical methodologies and new data

The MAKSWELL project was set up to help strengthening the use of evidence and information on well-being and sustainability for policy-making in the EU, as also the political attention to well-being and sustainability indicators has been increasing in recent years. Traditionally sample surveys are the data source used for measurement frameworks for well-being and sustainability. Over the last decades more and more new, alternative data sources become available. Examples are administrative data like tax registers, or other large data sets - so called big data - that are generated as a by-product of processes not directly related to statistical production purposes. In Deliverables 2.1, 2.2 as well as 3.1, 4.1 and 4.3 it is discussed in detail how these new data sources can be used in the production of official statistics and measurement frameworks for well-being and sustainability indicators. This Deliverable extends on the experiences obtained in these preceding deliverables by pointing out the needs for new data sources and methods in this context

Competitividade do Brasil no mercado internacional de aglomerado Brazil´s competivity in the international market of particleboard

Este estudo objetivou caracterizar a estrutura do mercado internacional de aglomerado quanto à sua concentração e desigualdade, bem como decompor as variações nas exportações desse produto dos principais países participantes em efeito-crescimento do comércio mundial, efeito-destino e efeito-competitividade no período de 1998 a 2002. O nível de concentração e desigualdade favorece práticas anticompetitivas. O efeito-competitividade, composto por aspectos endógenos, não favorece o aumento das exportações brasileiras.<br>This study aimed to characterize the structure of the international market of particleboard in relationship to its concentration and inequality and to decompose the variations in particleboard export in the major participant countries in terms of world trade growth effect, destination effect and competitiveness effect from 1998 to 2002. Concentration level and inequality favor anti-competitive practices and competitiveness effect, composed by endogenous aspects and market conditions, such as international agreements, do not favor Brazilian export growth
