Appendix Two. Customized matching differences, 1980 to 1990 Notes: Only those MSAs/CMSAs are shown in which the county geography for the custom metropolitan area coding differs in 1980 from 1990. Thus these matching notes indicate departures from the 1990 MSA/CMSA recodes, NOT departures from the actual 1980 MSA/CMSA county geography. To determine the counties included in a particular metropolitan area custom coding for 1980, first refer to the county listing for 1990 custom MSA county geography (in Appendix One), then consult these matching notes to see the differences between 1980 and 1990. Counties included in 1980 which are not included in 1990 are listed in square brackets following a "+"; counties absent from 1980 which are present in 1990 are listed in square brackets following a "-". To help cross-referencing, MSAs/CMSAs for which notes are given are listed according to their sequence number in the 1990 county listing in Appendix One. 2) Los Angeles-Riverside-Orange County CMSA Balance of Riverside (outside Riverside city) not included because combined in county group with more populous non-metropolitan Imperial County.
