Podlaskie Province in terms of level of socio-economic development takes place before the last one in the country. For the government document "Report Poland 2030 - Development Challenges", considered the foundation for developing the National Strategy for Regional Development, Podlaskie was assigned to Category B - peripheral areas where development is to proceed on a process of diffusion effects in the growth centers. This means that only the use of endogenous sources of growth in the form of internal resources of the region. And abandoning redistributive practices in regional policy. This development program has its limitations. One of them is the effect of 'leaching' of human resources. The concept of the backwash effect was introduced to the theory of regional development by G. Myrdal in 1957. G. Myrdal by backwash effect means any significant adverse changes in trade, mi-gration, capital movements, which operate centripetally causing recessionary processes in less developed regions and increasing their distance in relation to the growth poles. In the province of Podlaskie the backwash effect is the ongoing process for many years. This phenomenon manifests itself in a fall in the number of inhabitants in the different subre-gions, counties and municipalities, the decline in the percentage of women in the age group from 19 to 29 in the general population and the growing proportion of women in this age group in the external and internal migration. An additional manifestation of these processes is "sucking" of labor resources through the poles of growth, revealing a balance of internal and external migration - with a large positive value in the centers and a large negative value in remote areas. Among those who emigrate, leaving the Podlaskie Province over 57% are women. Among immigrants aged 20-24 is two times more women than men. At the beginning of the XXI century, the towns and cities of Podlaskie have a greater outflow than inflow of population. But under a polarizing development model of growth cities are its main source. This article aims to identify barriers to the development of Podlaskie based on endogenous sources, as their resources, especially when labor resources and human capital are shrinking due to the backwash effects. Despite the expenditure incurred by residents for education, the effects of this investment goes to the center along with the 'washing' of human resources. That is redistribution of income from poorer regions, with small resource capital to richer with large pools of capital and favorable labor market situation.
