We do a lot of work on the scale of the life insurance sector: size, composition, channels, growth rates, persistency, and explore each of the companies and channels that form part of the sector in some detail as well. We also periodically work on models such as how many advisers are present in the market, the size and growth rate of groups, and the flow through the market of people most-likely to buy insurance.
From time to time it is essential to put those sector and market statistics into a wider context. That context for the market includes population, migration, workforce, employment, home ownership, and incomes and expenditure data. The sector exists in an economic context too: the size of the economy, its growth rate, growth rate per capita, and so on. I often start workshops by asking people how big the economy is, and how fast it is growing (and some other more specific industry stats too) - there are always a good number of people who have no idea. That tells me that when working on a plan for a new project, proposal, or opportunity, don't assume that the reader has all the context that you do. Make life easy for them and give them the context. Here, for example, is the Statistics NZ update on the economy to the end of September last year.
