Q: This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
Passage: As of 2012, Singapore total fertility rate (TFR) is 1.20 children born per woman, which represents a sub-replacement fertility rate and is one of the lowest in the world. Ethnic Chinese had a ferlility of 1.07 in 2004 (1.65 in 1990), while Malays had a TFR of 2.10 (2.69 in 1990). Both figures declined further in 2006. TFR for Indians was 1.30 in 2004 and 1.89 in 1990. The Singapore government has launched several highly publicised attempts to raise the fertility rate and increase awareness of the negative effects of an aging population, the elderly (65 and above) had constituted 9.9% of its population in 2012; this proportion is still significantly lower than that of many other developed nations, such as the United States (12%) and Japan (21.2%) .
A:
How many more percent were not 65 years of age or older in Singapore than in Japan?
