Codes and Frequencies
For persons who had at least one injury/poisoning episode in the past 3 months, INJPLANA reports the number of times a person's response is recorded as "not ascertained" when asked where she/he was at the time of injury. Persons who answered the question about where they were at the time of injury could list up to 2 places. If a person refused, her/his response was not ascertained, or responded "don't know" when asked about where she/he was at the time of an injury, the person was recorded as having no second place for THAT injury. The person may, however, have observations for places she/he was at the time of OTHER injuries for which she/he did not have an unknown (refused, not ascertained, don't know) response.
INJPLANA is a person-level variable and is derived from corresponding injury/poisoning episode-level data. This variable describes the location at the time of injury or poisoning.
INJPLANA is part of a series of variables initiated in 1997 that systematically report persons' injuries and poisonings, the cause, what the person was doing while sustaining the injury or poisoning, and where she/he was at the time of the injury or poisoning. For related variables and additional information, please see the User note on Injuries and Poisonings or use the IPUMS NHIS search function and drop-down menus.
Prior to 2000, persons were asked about injuries and poisonings separately; in 2000, these categories were combined and persons were asked about the causes, activities, and locations related to injury and poisoning episodes at the same time.
In 2000 a screening question regarding the number of injuries or poisonings that were serious enough to seek medical attention was reworded and caused a marked decrease in the number of persons reporting injuries. The question was changed back to the originally intended wording in subsequent years. Despite the significant decline in the overall number of injury and poisoning episodes reported in 2000, the percentage distributions of episodes for the location at the time of injury or poisoning are comparable across time. Response categories change over time as certain locations of injuries become more or less common. For greater detail on these changes, please see the User Note on Injuries and Poisonings .
