Indicators describing the migration of population and revenues of local administrative units of the Kraków Metropolitan Area are presented and compared in this paper. A review of ideas on how to determine the number of Polish metropolitan statistical areas is also presented. The rank of Polish metropolitan statistical areas in world city rankings made by international publications is examined. Revenues of gminas from their own sources and total revenues of gminas are studied in the paper. Changes in revenue over time and location-dependent differences in revenue are analysed. However, the available data only allow for an examination of gminas without separating urban gminas from rural ones Substantial differences exist in the influx of revenue, both in terms of temporal and spatial changes. In order to summarise and evaluate the relevant social and economic processes, net migration of population and total revenue of gminas in the study area have been analysed. Furthermore, a classification of areas has been developed to describe the relevant areas as being of a certain type.

The present paper analyzes the spatial distribution of the largest companies in the world with headquarters in Europe. The impact of the economic crisis on changes in their revenues and profit is also highlighted. Spatial differences in the number of the Europe-located headquarters of the biggest companies (included on the Forbes Global 2000 list), their revenues and profits in 2006 and 2012 were also shown. It has been shown that in the period taken into consideration, the number of said headquarters located in the analyzed region decreased. At the same time, the division into Eastern Europe and Western Europe was clearly marked. The former is characterized by an increase in the number of headquarters, while the latter observed a decrease in said number. Also observed was the slight impact of the economic crisis on the income of companies from the Forbes Global 2000 list. Their revenue increased, but the pace was significantly lower than in non-European countries. It has also been observed that a higher revenue growth can be noticed in Eastern Europe. In addition, the signs of the economic crisis have been observed in the dynamics of profits of analyzed companies. In over 30% of European countries a decrease in profits of the analyzed companies was noted. Moreover, the economic crisis has caused the de-centralization of location of the headquarters of the biggest companies, which resulted in a larger number of cities where the HQs existed.

The purpose of the study was to determine the level of resilience of the command and control function via its dominant sector in cities in the United States and forecast the level of resilience for the period up to 2025. Changes in the WECI index were used to analyze this issue. The index is calculated based on standardized values of financial data of companies located in major metropolitan areas with a special focus on economic potential and the variety of sectors present. The number of corporate headquarters decreased in most cities in the U.S. (designated world economic centers) in the period 2006 – 2016, while the resilience of their main sectors increased. The most important WECs in the United States today are New York, Chicago, Houston, and San Jose. Research has shown that the resilience of U.S. cities tended to increase in a lagging manner with respect to the market value of U.S. companies following the 2008 global financial crisis. The forecast for 2025 suggests that the leading WECs in the U.S. will be New York, Chicago, San Jose, and San Francisco. No spatial patterns were noted in future changes in WECI values. Both decreases and increases in WECI values occur more or less evenly across the United States. Changes in U.S. WECI values also do not appear to be related to a one specific sector of the U.S. economy.

The descendants of the Maya living in modern-day Mexico distinguish themselves via language and advanced culture with respect to all other ethnic groups in the country. Features characteristic of the Maya include their dress, customs, and traditional living quarters. Their unique style of home construction is the result of their social and economic status and benefits generated by this form of traditional architecture. However, a number of factors are causing a decline in this traditional form of home construction. Two related factors are modernization and development in rural areas in Mexico. Another key factor is the perception that traditional ways of life and forms of housing are forms of backwardness. This is a view held by many in Mexican society. Many individuals have forgotten that traditional forms of architecture yield certain benefits unavailable elsewhere including the use of natural materials and technologies, ability to create ethnic and regional identity via housing traditions, and traditional ways of life that help the poor survive. All of these reasons may serve as an important basis for action that is designed to help foster sustainable development on a social level and a regional level. One additional reason to protect traditional ways of life is related to the promotion of tourism in a given geographic region. The present study examines traditional home construction, as practiced by the modernday Maya inhabitants of three Mexican states in the Yucatan Peninsula: Campeche, Quintana Roo, Yucatán. The study relies on statistical data obtained from the Mexican census: Encuesta Intercensal 2015 en Mexico. It also uses data obtained from other sources including fieldwork in the region. The study yields key characteristics of traditional housing and their distribution across geographic space in the study area.

Large corporations are an important aspect influencing the status of the city in the international context. The aim of this article is to determine the level of development of the command and control functions of cities in Central and Eastern Europe. These functions are defined on the basis of revenues from sales and net income of 600 corporations whose headquarters are located in Central and Eastern Europe for the years 2008 and 2012. The impact of each sector was also examined. During the economic slowdown in 2008–2012, revenues from sales and net income of the examined corporations slightly increased. The highest level of development of control and management functions has been observed in two capitals: Prague and Warsaw. In addition, a decrease in the number of cities in which the head offices were located was noted, which is different from the trend observed on a global scale.

This study takes into account the most important companies that have their head office in Central and Eastern Europe. The authors try to answer the question of how the city’s position will change due to deep crisis of the dominant sector in the city. The stability index was created, based on economic results achieved by individual corporations and their sectoral diversity. It illustrates the economic stability of urban centers in the case of global fluctuations. The most resistant to the crisis proved to Warsaw, Prague and Budapest. Impact on the location of the most resilient cities is the distance from the EU-15 and the political influence of the Soviet Union is visible in the region in 1945–1990 and the armed conflict in the former Yugoslavia. In addition, the cities studied despite having a small impact on the global economy are characterized by a fairly large international connections.

Research which concern delimitation, the function, and the competitiveness of Polish metropolitan areas has developed on a grand scale over the past few years. Relatively small portion of it has been devoted to the subject of migration processes in Polish metropolises. This article presents an analysis of structures, intensity and the directions of migration in the following metropolitan areas: Warszawa, Krakow, Katowice, Lublin and Bydgoszcz-Torun, in the years 2000-2005. A typology of migration in poviat districts constituting respective areas has been carried out. The analysis has shown that the processes of suburbanization in the researched areas are at different stages of development. The most advanced ones are noticed in the Warszawa Metropolitan Area, while in Lublin they are not visible yet.
