TASK DEFINITION: This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.
PROBLEM: Passage: Under a much broader definition (including people that have given up searching for employment) two different studies determined the unemployment rate to be 36.7% (2004) and 51.2% (2008), respectively. This estimate considers people in the Informal sector as employed. 72% of jobless people have been unemployed for two years or more. Labour and Social Welfare Minister Immanuel Ngatjizeko praised the 2008 study as "by far superior in scope and quality to any that has been available previously", but its methodology has also received criticism. The total number of formally employed people stood at 400,000 in 1997 and fell 330,000 in 2008, according to a government survey. The NSA 2012 study counted 396,000 formal employees. Of annually 25,000 school leavers only 8,000 gain formal employment-largely a result of a failed Education in Namibia.
Question: Were more people employed in 1997 or 2008?

SOLUTION: date
