The variables include country, year, normal and early pension age for men and women, as well as extra notes that provide additional information. Most of the data was extracted from the Social Security Administration (SSA) (https://www.ssa.gov/policy/docs/progdesc/ssptw/) and the International Social Security Association (ISSA) website (https://www.issa.int/databases/country-profiles), which detail pension systems in different countries. The dataset is provided in Excel and CSV formats.</abstract><sumDscr/></stdyInfo><method><dataColl><sources/></dataColl><anlyInfo/></method><dataAccs><setAvail/><useStmt/><notes type="DVN:TOU" level="dv">&lt;a href="http://creativecommons.org/publicdomain/zero/1.0">CC0 1.0&lt;/a></notes></dataAccs><othrStdyMat/></stdyDscr><otherMat ID="f13443592" URI="https://dataverse.harvard.edu/api/access/datafile/13443592" level="datafile"><labl>pension_age.csv</labl><notes level="file" type="DATAVERSE:CONTENTTYPE" subject="Content/MIME Type">text/comma-separated-values</notes></otherMat><otherMat ID="f13443593" URI="https://dataverse.harvard.edu/api/access/datafile/13443593" level="datafile"><labl>pension_age.xlsx</labl><notes level="file" type="DATAVERSE:CONTENTTYPE" subject="Content/MIME Type">application/vnd.openxmlformats-officedocument.spreadsheetml.sheet</notes></otherMat><otherMat ID="f13448279" URI="https://dataverse.harvard.edu/api/access/datafile/13448279" level="datafile"><labl>readme.txt</labl><notes level="file" type="DATAVERSE:CONTENTTYPE" subject="Content/MIME Type">text/plain</notes></otherMat></codeBook>
