A hierarchical file is one that contains information collected on multiple units of analysis where each unit of analysis is subordinate to another unit. For example, if the physical housing structure is one unit, and individual persons within the structure is another unit, the person records are subordinate (e.g. related to) the housing unit. An example would be the Current Population Survey Annual Demographic File which has household, family, and person units of analysis. Studies that include data for different units of analysis often link those units to each other so that, for instance, one can analyze the persons as they group in a structure. Such studies are sometimes referred to as having a relational structure.
A format for storing hierarchical files . Each unit of analysis has its own record structure or record type . Different units of analysis do not necessarily have the same number of bytes or characters as the records for other units of analysis. In order to give such a file a common physical record length , short logical records are typically "padded" with blanks so that they will all be the same physical record length. A hierarchical file can be also be stored in a rectangular file . For instance, the Survey of Income and Program Participation is distributed both ways; users can choose the format they prefer. Typically, the hierarchical file structure is more space-efficient but more difficult to use.
