These questions are useful because they distinguish between two possible causes of declining fertility. If someone says they want a child, but don&#8217;t intend to have one, it seems like something is standing in their way. In that case, changing circumstances might change their intentions. But if they don&#8217;t want children, that might be less likely to change.<\/p>\n\n\n\n<p>Let&#8217;s start with stated desires. The following figure shows the fraction of men who say they want a child \u2014 or another child if they have at least one \u2014 grouped by decade of birth.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"997\" height=\"565\" src=\"https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent05-1.png\" alt=\"\" class=\"wp-image-1532\" srcset=\"https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent05-1.png 997w, https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent05-1-300x170.png 300w, https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent05-1-768x435.png 768w, https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent05-1-476x270.png 476w\" sizes=\"auto, (max-width: 997px) 100vw, 997px\" \/><\/figure>\n\n\n\n<p>Men born in the 2000s are less likely to say they want to have a child \u2014 about 86% compared to 92% in previous cohorts.

Women born in the 1990s are in line with previous generations.&nbsp;<\/p>\n\n\n\n<p>Maybe surprisingly, men are more likely to say they want children.&nbsp; For example, of young men (15 to 24) born in the 2000s, 86% say they want children, compared to 76% of their female peers. Lyman Stone <a href=\"https:\/\/substack.com\/@lymanstone\/p-156994214\">wrote about this pattern recently<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What About Intentions?<\/h2>\n\n\n\n<p>The patterns are similar when people are asked whether they <em>intend<\/em> to have a child.

The following figure shows the percentage of men who <em>want<\/em> a child minus the percentage who <em>intend<\/em> to have a child.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"997\" height=\"565\" src=\"https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent08-1.png\" alt=\"\" class=\"wp-image-1534\" srcset=\"https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent08-1.png 997w, https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent08-1-300x170.png 300w, https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent08-1-768x435.png 768w, https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent08-1-476x270.png 476w\" sizes=\"auto, (max-width: 997px) 100vw, 997px\" \/><\/figure>\n\n\n\n<p>Among young men, the difference is small \u2014 most people who want a child intend to have one. The difference increases with age. Among men in their 30s, a substantial number say they would like another child but don&#8217;t intend to have one.<\/p>\n\n\n\n<p>Here are the same differences for women.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"997\" height=\"565\" src=\"https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent07-1.png\" alt=\"\" class=\"wp-image-1535\" srcset=\"https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent07-1.png 997w, https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent07-1-300x170.png 300w, https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent07-1-768x435.png 768w, https:\/\/www.allendowney.com\/blog\/wp-content\/uploads\/2025\/03\/nsfg_intent07-1-476x270.png 476w\" sizes=\"auto, (max-width: 997px) 100vw, 997px\" \/><\/figure>\n\n\n\n<p>The patterns are similar \u2014 among young women, most who want a child intend to have one. Among women in their 30s, the gap sometimes exceeds 20 percentage points, but might be decreasing in successive generations.<\/p>\n\n\n\n<p>These results suggest that fertility is lower among people born in the 1990s and 2000s \u2014 at least so far \u2014 because they want fewer children, not because circumstances prevent them from having the children they want.<\/p>\n\n\n\n<p>From the point of view of reproductive freedom, that conclusion is better than an alternative where people want children but can&#8217;t have them. But from the perspective of public policy, these results suggest that reversing these trends would be difficult: removing barriers is relatively easy \u2014 changing what people want is generally harder.<\/p>\n\n\n\n<p>DATA NOTE: In the most recent iteration of the NSFG, about 75% of respondents were surveyed online; the other 25% were interviewed face-to-face, as all respondents were in previous iterations. Changes like this can affect the results, especially for more sensitive questions. And in the NSFG, <a href=\"https:\/\/substack.com\/@lymanstone\/p-156994214\">Lyman Stone has pointed out<\/a> that there are non-negligible differences when we compare online and face-to-face responses. Specifically, people who responded online were less likely to say they want children and less likely to say they intend to have children. At first consideration, it&#8217;s possible that these differences could be due to social desirability bias.<\/p>\n\n\n\n<p>However, people who responded online also reported substantially lower parity (women) and number of biological children (men), on average, than people interviewed face-to-face \u2014 and it is much less likely that these responses depend on interview format. It is more likely that the way respondents were assigned to different formats depended on parity\/number of children, and that difference explains the observed differences in desire and intent for more children. Since there is no strong evidence that the change in format accounts for the differences we see, I&#8217;m taking the results at face value for now.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The most recent data from the National Survey of Family Growth (NSFG) provides a first look at people born in the 2000s as young adults and an updated view of people born in the 1990s at the peak of their child-bearing years.
