Open to the public, the interactive platform allows users to create and download profiles for the countries or territories they are interested in.
Because the data is updated every 24 hours, users can be confident that they are accessing the most up-to-date information available.
The information is made available by bringing together harmonised, validated data from 12 international sources.
The Atlas provides information on 60 different indicators related to migration, asylum, integration, demography, and development."
Schools Project on Poland
https://projectpolish.com/
"Schools Project on Poland is an educational project led by Project Polish Ltd […] a nonprofit making company, dedicated to support students and teachers across the country. The project aims to promote the heritage of past generations and the positive contribution made by Poles to the cultural, economic and social life in the United Kingdom and has the support of both the Polish Embassy in Warsaw and the British Embassy in London. 2018 marks the centenary of the state of Poland regaining its independence. Following the First World War and after spending 123 years divided amongst the three neighboring powers: Russia, Germany and Austro-Hungarian Empire, Poland regained its sovereignty on 11 November 1918. We see this as an opportunity to celebrate the connections between Poland and the UK and the varied contribution of Polish people to British life." [Taken from: https://projectpolish.com/about-us/]
