Statistical software may make it easier to analyze large amounts of data, but most IHGIS data tables are relatively small. If you are looking for data from a particular country, send a note to We may have data that we could bump up in the queue.ĭo I need special statistical software like SPSS, SAS, or Stata to use IHGIS data? Back to TopĪbsolutely not! Any spreadsheet software like Microsoft Excel will work fine, and even that technically is not required. We also have data for many more datasets at various stages in the processing pipeline. You can find a summary of the datasets available in IHGIS on the Dataset Descriptions page. What countries does IHGIS have data for? Back to Top All shapefiles are aligned to the Large Scale International Boundaries (LSIB) dataset from the U.S.Department of State to ensure that the boundaries of neighboring countries will coincide. We then adjust the units in the geographic data as necessary to align with the units represented in the data tables. Common sources include GADM, the UN Second Administrative Level Boundaries (SALB) project, and the Food and Agriculture Organization's Global Administrative Unit Layers (GAUL). Most often, however, we identify boundary data in an international data source to use as a starting point. When possible, we obtain source shapefiles from the country's national statistical office or geographic agency. The GIS boundary files draw on a variety of data sources. Often, you will be able to find the original source documents on these sites, but there is no guarantee that they are still available. Links to the national statistical office home pages for the countries for which IHGIS has data are available on the Source Organizations page. In some cases, data were published as Excel files or other data formats. Most of these reports were published as PDF documents containing data tables as well as narrative text. Most IHGIS data were originally obtained from census results reports published on national statistical office websites. What is the source of IHGIS data? Back to Top No individual-level records, with or without personally identifiable information, are included anywhere in IHGIS. IHGIS specifically provides spatially aggregated census data: data summarizing individuals within particular areas, such as states or counties, where the "individuals" might be persons, housing units, farms, chickens, or any other features that were at some point counted in a census. I have a suggestion for how you can improve your website! Do you want to hear it?Īggregate data summarize sets of individuals through counts, sums, means or other aggregate statistics. What coordinate system are the GIS files in? IHGIS Project Questions OK, I downloaded the data tables and the GIS files. I downloaded some data tables and I want to map them. I don’t have Esri ArcGIS! Can I still map IHGIS data? Something is wrong with the data I downloaded. What do the field names (e.g., AAA001, ABA005) in an IHGIS data file mean? Why do I receive so many data files in my downloaded zipped file? How long does a data extract take?
