From foreign affairs to family planning, The Straits Times looks at how the focus of Prime Minister Lee Hsien Loong's National Day Rallies has changed over the last decade. We grouped different parts of his speeches into seven broad categories and found that while time spent on topics like the economy and foreign affairs has shortened, he has spent more time talking about education. Others like immigration spike in certain years when the issue gets hot.

Update (Aug 19, 2014): Figures and quotes for National Day Rally 2014 added.
Methodology: The percentage for each topic was calculated by grouping all sentences in each rally speech into seven broad topics where possible, and then dividing the word count for each by the total word count for that year. The lines that did not fall into any of the seven categories were grouped under "Others".
