The term was used 16 times[4][5] by Rudd during the leaders debate on 21 October 2007. Despite calls[5] for a definition during the election campaign, the term remained undefined. The ambiguous nature of the term allowed evasion of definitive policies throughout the campaign.[5]
In the lead up to the federal budget of May 2008 the term continued to cause confusion and the scope was expanded by the Treasurer and the Prime Minister to include, among others, "a single person who is a pensioner or a self-funded retiree, or someone who is being provided care by a carer". In fact neither the prime minister or the treasurer was prepared to exclude anyone from the definition.[6]
"When you're talking about "working families", who exactly are you talking about?" (Interviewer: Steve Cannane[7])
"I'm talking about those people on modest incomes. If you're talking about Sydney, you're talking about a principal income earner who might be earning $50–60 thousand a year, and a secondary income earner, who will be working part-time, and could pull in anywhere between 20 or 30 thousand dollars per year. These are people who work very hard, they are hit by rising inflation, which is why tackling inflation in this Budget is so important, they are hit by the rising cost of living, and until recent times they have been hit by a rising proportion of taxation...."[8]
This definition was reinforced by Rudd later the same day, saying, "If you’re a working family on $50,000 a year, it means, or a worker on $50,000 a year...."[9]

Then, it was 400,000 more on hospital waiting lists—now, it is almost 300,000 off. Then, it was crime doubled—now, it’s crime down by over a quarter." — Alan MilburninAgenda: magazine of the Association of Labour Councillors, winter 2004/5 ("Britain is Working"Archived 2006-02-10 at the Wayback Machine)
^"Turning to tax allowances, the married couples' allowance has been abolished, which is a strange move for a government who profess to support the family. They have abolished the MIRAS tax relief which has hit home-buyers. The change to the allowances for couples with children—the new children's tax credit—which is tapered away for higher rate taxpayers, will affect hardworking families on middle incomes." — Lord Northbrook recorded in Hansard, 1999-07-23 (column 1229)
