This report is the first of the Current Estimates series to present data entirely from interviews using the "person approach." Prior to July 1967, data for this series of reports were obtained from interviews using the "condition approach." During this period July 1967-June 1968, a split sample methodology was used, in which one-half of the sample population was interviewed using the "condition approach," and the other half using the "person approach." For a brief discussion of these two versions of the questionnaire design and the rationale for changes made in the collection procedure; see Appendix III, Series 10, No. 52. A forthcoming Series 2 report will present estimates based on the data collected during the year in which the split-sample was used and will discuss some of the implications of the change in data-collection procedures. The present report is also the first of this series to utilize the Eighth Revision of the International Classification of Diseases, Adapted(ICDA), in the classification of acute conditions. A more detailed discussion of the impact of this classification scheme on acute conditions data will be presented in a forthcoming report on acute conditions for the period July 1968-June 1969.
