2017 San Diego County Demographics - Veterans: Period of Service

Veterans: Period of Service.
Veterans: Civilians who have served (even for a short time), but are not currently serving, on active duty in the U.S. Army, Navy, Air Force, Marine Corps, or the Coast Guard, or who served in the U.S. Merchant Marine during World War II. People who served in the National Guard or Reserves are classified as veterans only if they were ever called or ordered to active duty. People who indicate that they had ever served on active duty, were currently on active duty, were asked to indicate the period or periods in which they served. Currently, there are 9 periods of service on the ACS questionnaire. Respondents are instructed to mark a box for each period in which they served, even if just for part of the period. The periods were determined by the Department of Veterans Affairs (VA) and generally alternate between peacetime and wartime.

退伍军人：服役时期。
退伍军人系指曾短期服役但现未在美军陆军、海军、空军、海军陆战队或海岸警卫队中现役，或在二战期间曾在美国商船队服役的平民。在国民警卫队或预备役部队服役的人员，只有在曾被召唤或命令执行现役任务时，方被归类为退伍军人。凡表明曾执行现役任务、现正执行现役任务或被要求表明其服役时期的人员，均需标明其服役的时期或时期。目前，美国社区调查问卷中设有9个服役时期选项。受访者被指示为每个曾服役的时期勾选一个方框，即便仅为部分时期。这些时期由美国退伍军人事务部（VA）确定，通常交替出现在和平时期和战争时期。
