The purpose of this project is to add the property valuation bands to the Census Household Sampling frame, by matching to the Local Property Tax (LPT) file. This project is being conducted as part of the sample design procedure for the Q3/Q4 2023 Household Finance and Consumption Survey (HFCS). The valuation bands will be used, along with home ownership, as a proxy measure for wealth. This 'wealth' indicator will then be used for stratification purposes.

One-off

Social Data Collection expect to obtain and enhance Census Sampling Frame, which includes Local Property Tax valuation bands. This will allow for the sample design of the 2023 Household Finance and Consumption Survey to include a 'wealth' indicator as part of the stratification.

 This project will compliment previous reports produced by the Department of Education and Skills related to Early School Leavers. 

This project will allow statistical analysis administrative data allowing the tracking of early school leavers and school completers a year after they leave school (to potentially include multiple years depending on the data available with the range being explored). 
This analysis requires access to the analysis tier data flows.

This is a pilot project to develop a process to produce statistical analysis of diversity of the workforce in the public service.

This project is expected to provide aggregated statistical data on Regional Health Areas (RHAs).

The Educational Longitudinal Database (ELD) is a statistical framework for the compilation and analysis of learner outcomes over many years. The ELD provides the basis for a series of projects that the CSO has established in collaboration with Irish public sector bodies to examine learner outcomes across a range of educational levels and programmes.

The project involves micro-data linking of Structural Business Statistics and other business statistics. The microdata sets have been collected and stored in a standardised format specified by the Eurostat Task Force co-ordinators, and matching between the data sources will begin in or after September 2014. The project will result in the creation of longitudinal datasets of enterprise data for the years 2008-1012 for analysis and the production of standardised output for descriptive, longitudinal and impact analysis.

The goal of this data matching project is to obtain statistical information and insight around the integration of young migrants into Irish society. Young immigrants may be measured using a combination of Census and administrative data.
The proposed analysis will look at indicators of integration such as unemployment, self-employment, property ownership and educational attainment either in the Census and/or administrative data and compare to the non-immigrant Irish resident population.

Outputs will be in the form of a report(s) with graphs and tables of aggregate data (including tables available on pxstat)
