As recorded by the source, Moroccans ranked as the foreign nationality with more residents in Spain in 2023, closely followed by Romanians. After years of losing its foreign population, Spain’s immigration figures started to pick up in 2015, with the number of people that moved to the Mediterranean country surpassing the number of foreigners that decided to leave.

A matter of balance The net migration rate of Spain changed its course mainly due to the great inflow of foreigners that move to reside in the Mediterranean country. Spain’s immigration flow slowed down after the 2008 financial crisis, albeit the number of foreigners that opted to change their residence saw a significant growth in the last years. In 2022, Colombians ranked first as the foreign nationality that most relocated to Spain, distantly followed by Moroccans and Ukranians.

Spain does not have the highest number of immigrants in Europe In recent years, the European Union confronted a rising number of refugees arriving from the Middle East. Migration figures show that Germany accommodated approximately 15 million foreign-born citizens, ranking it as the country that most hosted immigrants in Europe in 2022. By comparison, Spain’s foreign population stood slightly over seven million, positioning the Western Mediterranean country third on the European list of foreign-born population. Unfortunately, thousands of persons have died ore gone missing trying to reach Spanish territory, as more and more irregular migrants opt to use dangerous maritime routes to arrive at Southern Europe from Africa's coasts.

The SMARTDEST Neighbourhood Change Database (hereinafter referred to as, SNCD) is the result of an 8-month co-creation process undertaken in the framework of a CityLab in the city of Barcelona, Spain. This activity was part of a broader research project funded under the Horizon 2020 programme (SMARTDEST, 2020-2023; Grant agreement ID: 870753). The CityLab in Barcelona (June 2022-February 2023) brought together a heterogeneous group of stakeholders and end-users concerned with the diagnostic of tourism-driven neighbourhood change in Barcelona. CityLab participants have been asked to identify measurable indicators that could enable a rigorous estimation of the social costs of tourism in Barcelona in terms of its impact on housing affordability and population turnover. The SNCD in its current shape (release version 1.0) encompasses 32 variables. All these variables are available for the 4 years comprised between 2016 and 2019, aggregated at the census tract level.

The Public Health Agency of Barcelona provides the most accurate indicator to identify the most vulnerable population at a socioeconomic level. It is the percentage of the population from the age of 16 that is illiterate or uneducated with respect to the total within this age group. The socio-economic situation of this segment of the population can favor vulnerability to a heat wave.

Reporting data from the Mosquito Alert citizen science system, active catch basin surveillance, and mosquito trap surveillance used in "Assessing and Correcting Neighborhood Socioeconomic Spatial Sampling Biases in Citizen Science Mosquito Data Collection."

The file named mosquito_alert_adult_bite_reports_Barcelona_2014_2023.Rds includes all adult mosquito and mosquito bite reports received from Barcelona Municipality from the start of the Mosqiuto Alert project in 2014 through the end of 2023. The file named mosquito_alert_validated_albopictus_reports_Barcelona_2014_23.Rds includes all expert-validated Ae. albopictus reports received from Barcelona Municipality during the same time period. The data is stored as RDS files and contain the following fields:

• year - the year in which the report was made. Class = dbl.
• date - the date om which the report was made. Class = date.
• type - the report type, either adult mosquito ("adult") or mosquito breeding site ("site"). Class = chr.
• lon - the longitude of the report location. Class = dbl.
• lat - the latitude of the report location. Class = dbl.
• validation_score - Entolab validation score. Either 1 (possible Ae. albopictus) or 2 (probable Ae. albopictus). This field is present only in the validated reports data.

The file named active_catch_basin_drain_data.Rds includes information about all catch basin drains in Barcelona Municipality in which the Barcelona Public Health Agency (ASPB) detected mosquito activity as part of its continuous monitoring and control of mosquitoes from 2019 through 2023.

• se_expected - sampling effort for the 0.025 degree lon/lat sampling cell in which the catch basin drain lies during the year in which the ASPB detected mosquito activity in the drain. This value is taken from the SE_expected variable in the sampling_effort_daily_cellres_025.csv.gz file available at https://zenodo.org/records/12602985. Sampling effort is estimated as the expected number of participants sending at least one report from the cell during the day in question given the the number of participants recorded in the cell that day and the amount of time elapsed since each one began participating in the project. Class = dbl.
• p_singlehh - proportion of single-member households in the population of the census tract in which the catch basin drain is located. Class = dbl.

Combined Longitudinal Study of the Second Generation in Spain data set, Waves 1 and 2. This is the publicly available version of the ILSEG data (ILSEG is the Spanish acronym for Investigación Longitudinal de la Segunda Generación, Longitudinal Study of the Second Generation). Questions address the situations and plans for the future of young Spaniards who are children of immigrants to Spain, who were living in Madrid and Barcelona and attending secondary school in 2007-2008 and the 2011-2012 follow up). The longitudinal study of the second Generation (ILSEG in its Spanish initials) represents the first attempt to conduct a large-scale study of the adaptation of children of immigrants to Spanish society over time. To that end, a large and statistically representative sample of children born to foreign parents in Spain or those brought at an early age to the country was identified and interviewed in metropolitan Madrid and Barcelona for wave 1. In total, almost 7,000 children of immigrants attending basic secondary school in close to 200 educational centers in both cities took part in the study. Because of sample attrition, wave 2 introduced a replacement sample. Additionally, a native born sample of children of Spaniards was also included to enable comparisons between native and immigrant-origin populations of the same age cohort.Topics include basic demographics, national origins, Spanish language acquisition, foreign language knowledge and retention, parents' education and employment, respondents' education and aspirations, religion, household arrangements, life experiences, and attitudes about Spanish society. Demographic variables include age, sex, birth country, language proficiency (Spanish and Catalan), language spoken in the home, number of siblings, mother's and father's birth country, religion, national identity, parent's sex, parent's marital status, parent's birth year, and the year the parent arrived in Spain.
