Between 1820 and 1957, at least 400,000 people migrated from Poland to the United States. Due to Poland's complicated border-history, many Polish migrants were recorded as having other nationalities, particularly Austrian, German and Russian (all migrants who claimed to be Polish between 1899 and 1919 were recorded as being one of these other nationalities), therefore the exact number of Polish migrants to the United States during this time is unknown. From 1920 onwards, Poland's sovereignty and independence was acknowledged by the United States government (US President Wilson was instrumental in helping to establish the independent Republic of Poland), and the figures become more reliable. The years with the highest number of documented Polish migrants to the US was after the First World War in the early 1920s, with almost 100,000 Poles migrating in 1921 alone, although the number fell below 10,000 again by 1925.

The number of immigrants in Poland reached nearly ****** in 2023 and increased by seven percent compared to the previous year. Population in Poland Since 2010, the population of Poland has been decreasing year by year. In 2022, Poland’s society was about ******* lower than in 2012. This result is influenced by birth and death rates, as well as migration rate. Many factors are contributing to these rates. For birth rates, the number of women of reproductive age, changing attitudes toward having many children at a young age, household income, and government incentives such as the 500+ program must be considered. Regarding the death rate, it is necessary to consider the age and number of seniors, as well as medical progress. Therefore, it is estimated that Poland’s population will decrease to slightly over **** million in 2100. Migration in Poland In 1950, Poland had the lowest net migration level, amounting to *******, where more than ****** chose to emigrate, and only about ***** decided to immigrate to Poland. In contrast, net migration in 2023 has reached ***** people, which means more people decided to live in Poland than to leave it. That year, the most Poles who decided to emigrate moved to Ukraine, Germany, and the United Kingdom. By comparison, Poland also had the most significant number of immigrants from Ukraine, the United Kingdom, and Germany.

The majority of immigrants in Poland in 2023 were from Ukraine (******), a decrease of ** percent compared to the previous year. Immigration to Poland for different reasons In 2022, nearly ****** people immigrated to Poland for permanent residence, of which most came from Ukraine, the UK, and Germany, respectively. Furthermore, the majority of immigrants for temporary stay in Poland in 2022 were from Ukraine (****** immigrants), a decrease of *** percent compared to the previous year. In 2023, most Ukrainian citizens chose Poland as a place for economic emigration. The main reason for that choice was geographical and cultural proximity. Nearly every second respondent valued the low language barrier, and for every third person, the motivation was earnings. Poles attitudes toward Russia’s war with Ukraine In 2022, most Poles had a negative attitude toward Russia’s invasion of Ukraine. Poles’ biggest concerns about the Russia-Ukraine war were the military threats from Russia and the impact of the war on the condition of the Polish economy. After the Russian invasion of Ukraine in February 2022, Poles proved their support for Ukrainians. One of the most common forms of support for refugees fleeing the Russia-Ukraine war to Poland was to provide blankets, food, and hygiene items. Four out of 10 Poles donated money to a charity fundraiser and volunteered in organizations.

Today, German is the most common ethnic identity claimed by citizens of the United States. Between 1820 and 1957 over 6.6 million Germans migrated to the United States, particularly in the mid to late 19th century. The amount of migrants from other Central European countries to the US, primarily from the Austro-Hungarian Empire, was over 4.4 million between these years. This was mostly due to the weakening economy, political instability and social inequality of Austria-Hungary during this time, before the outbreak of the First World War caused migration from the region to drop from almost 280,000 in 1914, to below 20,000 in 1915. Approximately 440,000 Polish people were documented as having arrived in the US between 1820 and 1957, however this is much lower than the actual number of ethnic Poles who migrated in this time period, as Poland did not have officially recognized borders until 1918 and its citizens were often recorded with other nationalities.

Although the American Community Survey (ACS) produces population, demographic and housing unit estimates, the decennial census is the official source of population totals for April 1st of each decennial year. In between censuses, the Census Bureau's Population Estimates Program produces and disseminates the official estimates of the population for the nation, states, counties, cities, and towns and estimates of housing units for states and counties..Information about the American Community Survey (ACS) can be found on the ACS website. Supporting documentation including code lists, subject definitions, data accuracy, and statistical testing, and a full list of ACS tables and table shells (without estimates) can be found on the Technical Documentation section of the ACS website.Sample size and data quality measures (including coverage rates, allocation rates, and response rates) can be found on the American Community Survey website in the Methodology section..Source: U.S. Census Bureau, 2022 American Community Survey 1-Year Estimates.Data are based on a sample and are subject to sampling variability. The degree of uncertainty for an estimate arising from sampling variability is represented through the use of a margin of error. The value shown here is the 90 percent margin of error. The margin of error can be interpreted roughly as providing a 90 percent probability that the interval defined by the estimate minus the margin of error and the estimate plus the margin of error (the lower and upper confidence bounds) contains the true value. In addition to sampling variability, the ACS estimates are subject to nonsampling error (for a discussion of nonsampling variability, see ACS Technical Documentation). The effect of nonsampling error is not represented in these tables..The 2022 American Community Survey (ACS) data generally reflect the March 2020 Office of Management and Budget (OMB) delineations of metropolitan and micropolitan statistical areas. In certain instances the names, codes, and boundaries of the principal cities shown in ACS tables may differ from the OMB delineations due to differences in the effective dates of the geographic entities..Estimates of urban and rural populations, housing units, and characteristics reflect boundaries of urban areas defined based on 2020 Census data. As a result, data for urban and rural areas from the ACS do not necessarily reflect the results of ongoing urbanization..Explanation of Symbols:- The estimate could not be computed because there were an insufficient number of sample observations. For a ratio of medians estimate, one or both of the median estimates falls in the lowest interval or highest interval of an open-ended distribution. For a 5-year median estimate, the margin of error associated with a median was larger than the median itself.N The estimate or margin of error cannot be displayed because there were an insufficient number of sample cases in the selected geographic area. (X) The estimate or margin of error is not applicable or not available.median- The median falls in the lowest interval of an open-ended distribution (for example "2,500-")median+ The median falls in the highest interval of an open-ended distribution (for example "250,000+").** The margin of error could not be computed because there were an insufficient number of sample observations.*** The margin of error could not be computed because the median falls in the lowest interval or highest interval of an open-ended distribution.***** A margin of error is not appropriate because the corresponding estimate is controlled to an independent population or housing estimate. Effectively, the corresponding estimate has no sampling error and the margin of error may be treated as zero.

Desmin is a muscle-specific intermediate filament protein which forms a network connecting the sarcomere, T tubules, sarcolemma, nuclear membrane, mitochondria and other organelles. Mutations in the gene coding for desmin (DES) cause skeletal myopathies often combined with cardiomyopathy, or isolated cardiomyopathies. The molecular pathomechanisms of the disease remain ambiguous. Here, we describe and comprehensively characterize two DES mutations found in Polish patients with a clinical diagnosis of desminopathy. The study group comprised 16 individuals representing three families. Two mutations were identified: a novel missense mutation (Q348P) and a small deletion of nine nucleotides (A357_E359del), previously described by us in the Polish population. A common ancestry of all the families bearing the A357_E359del mutation was confirmed. Both mutations were predicted to be pathogenic using a bioinformatics approach, including molecular dynamics simulations which helped to rationalize abnormal behavior at molecular level. To test the impact of the mutations on DES expression and the intracellular distribution of desmin muscle biopsies were investigated. Elevated desmin levels as well as its atypical localization in muscle fibers were observed. Additional staining for M-cadherin, α-actinin, and myosin heavy chains confirmed severe disruption of myofibrill organization. The abnormalities were more prominent in the Q348P muscle, where both small atrophic fibers as well large fibers with centrally localized nuclei were observed. We propose that the mutations affect desmin structure and cause its aberrant folding and subsequent aggregation, triggering disruption of myofibrils organization.

Poland, a country rich in history and culture, is home to a diversity of traditions that are reflected in its Polish surnames. These surnames are not only a means of identifying people, but they also carry with them family histories and connections across generations. In this article, we will explore the most common surnames in Poland, analyzing their origin and meaning, as well as the fascinating evolution they have had over time. By learning about Polish surnames, we not only broaden our understanding of this nation, but we also celebrate the cultural heritage that these names represent. Join us on this journey through the identity and history of the Poles through their most characteristic surnames.

Net migration reached its lowest level in 1950 (-******) when the number of migrants arriving in the country was estimated at *****, compared to around ****** people departing. In 2024, there were more inflows than outflows, resulting in a net migration of nearly ***** people. Foreign migration of population For several years Poland has been witnessing a positive balance of migration. The number of immigrants reached ******, while emigration reached ****** in 2024. The main directions of permanent emigration are Germany and the United Kingdom. Immigrants coming to Poland to live permanently are mostly returning Polish emigrants. Hence, the most significant number of people came from the United Kingdom and Germany. Much larger is the scale of migration for temporary residence. There has been an increase in the number of immigrants temporarily staying in Poland recently. The number of economic immigrants is growing, especially Ukrainian citizens interested in taking up temporary employment. There is also a noticeable increase in the number of foreigners interested in continuing their education at Polish universities. The analysis of migration trends indicates that Poland is transforming from a typical emigration country into an emigration and immigration country. Internal migration of the population The period from 2017 to 2019 saw an increased number of internal movements. However, due to the outbreak of the coronavirus (COVID-19) pandemic, the number of internal migrants fell to ******* in 2020. As a result of internal migration, rural areas gained residents. The balance of migration for rural areas amounted to nearly ****** people. In Mazowieckie, Pomorskie, Małopolskie, Dolnośląskie, and Wielkopolskie region, the inflow of population was greater than the outflow. Therefore, internal migrations caused an increase in the population of those voivodeships. The remaining voivodeships recorded a decrease. The most significant population loss in 2020 was experienced by Lubelskie and Śląskie voivodeships — this trend has been maintained for several years.

Machine learning (ML) algorithms can handle complex genomic data and identify predictive patterns that may not be apparent through traditional statistical methods. They become popular tools for medical applications including prediction, diagnosis or treatment of complex diseases like rheumatoid arthritis (RA). RA is an autoimmune disease in which genetic factors play a major role. Among the most important genetic factors predisposing to the development of this disease and serving as genetic markers are HLA-DRB and non-HLA genes single nucleotide polymorphisms (SNPs). Another marker of RA is the presence of anticitrullinated peptide antibodies (ACPA) which is correlated with severity of RA. We use genetic data of SNPs in four non-HLA genes (PTPN22, STAT4, TRAF1, CD40 and PADI4) to predict the occurrence of ACPA positive RA in the Polish population. This work is a comprehensive comparative analysis, wherein we assess and juxtapose various ML classifiers. Our evaluation encompasses a range of models, including logistic regression, k-nearest neighbors, naïve Bayes, decision tree, boosted trees, multilayer perceptron, and support vector machines. The top-performing models demonstrated closely matched levels of accuracy, each distinguished by its particular strengths. Among these, we highly recommend the use of a decision tree as the foremost choice, given its exceptional performance and interpretability. The sensitivity and specificity of the ML models is about 70% that are satisfying. In addition, we introduce a novel feature importance estimation method characterized by its transparent interpretability and global optimality. This method allows us to thoroughly explore all conceivable combinations of polymorphisms, enabling us to pinpoint those possessing the highest predictive power. Taken together, these findings suggest that non-HLA SNPs allow to determine the group of individuals more prone to develop RA rheumatoid arthritis and further implement more precise preventive approach.
