<restrctn> In preparing the data file(s) for this collection, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution NCHS requires, under Section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.</restrctn> <restrctn> ICPSR obtained these data from the World Bank under the terms of a contract which states that the data are for the sole use of ICPSR and may not be sold or provided to third parties outside of ICPSR membership. Individuals at institutions that are not members of the ICPSR may obtain these data directly from the World Bank.</restrctn>
