First, the aging ofthe baby boom is not a single-point trend. Placing
the baby boom at age forty is not like placing the DowJones average
at 10,000. In the above analysis, we've assumed that the baby boomers
were born in 1960 and therefore that they turned forty in the year 2000.
But millions of baby boomers were younger and older in 2000-as young
as twenty-seven and as old as fifty-four. Thac's a big spread.

a trend that can be measured from a single point (in time)
This means that the trend cannot be measured from one point in time to another since it is about a generation of people who are naturally born at different points in time.

a trend with only one start date or point
another way of putting it.
Analysts would avoid having statistics based on a line form A to B as a single-point start and end point.
Here, as Simon says, there is a large range of start points for this study of baby-boomers as some are only 27 years old in 2000 (born in 1973) while others are 54 (in 2,000) so were born in 1946.

Because you need a statistically significant number of data points to infer a trend, you can’t draw a line between the start and end points and call it a trend.

: Not a question of what analysts would avoid, but of the characteristics of the data. It all depends what is being measured, but e.g. whether people born in year X are still alive in year Y is easier to assess than are weather patterns.

agree data required will depend on what is being measured, but was just giving another definition for the term posted

English term (edited):
not a single-point trend
not arbitrary
The base Dow is an arbitrary figure, it could equally have been set at 1 or 100,000. So this seems the simplest and most natural way of expressing the idea.
