In my usual perusing of the genealogy and DNA blogs I review almost daily, I saw this earlier this afternoon – 23andMe improves reports for Caribbean and Latin American customers: https://blog.23andme.com/ancestry/23andme-improves-reports-for-caribbean-and-latin-american-customers/. I removed the images and a few other items.
In the poem, Levins Morales acknowledges her diverse roots—a combination of African, European, and Indigenous American—but chooses to celebrate and identify with her Puerto Rican identity.
Today, the Americas are a genetic crossroads, home to many people like Levins Morales with identities forged by waves of migration and a fusion of cultures.
In our ongoing efforts to deliver a more intuitive and comprehensive 23andMe Ancestry Composition report, we’ve released a new feature called “Recent Ancestry in the Americas” for customers with ancestry from Central America, South America, and the Caribbean. In tandem with 23andMe’s Ancestry Composition report, this new feature enables these customers to explore their heritage in a more recent timeframe — following the mixing of historically separate populations that occurred in the Americas over the last few hundred years.
In addition, customers with ancestry from Jamaica, Haiti, and 10 other countries in the Caribbean may see an exciting new level of detail about places their ancestors may have lived, in the form of more granular maps. Over time, these maps will continuously update to reflect the growing size and diversity of 23andMe’s database.Recent Ancestry in the Americas

What’s included in this update?
In each of the three new reports, customers will see a brief genetic history of the region, a map highlighting sub-country regions where we have found evidence of their recent ancestry, and educational content to provide additional scientific and historical context. We’ve also included short stories that provide a sampling of aesthetics, flavors, and traditions that may inspire customers to connect with aspects of their heritage.
We encourage customers to contribute ideas for future stories by leaving feedback at the link included in each Ancestry Detail Report.
How can I find these new Ancestry Detail reports?
If you have ancestry from one of these regions, this new section will appear below your percentages in your Ancestry Composition report.
You can also access these new reports through Ancestry Overview, through the all-reports tab, or find them in Scientific Details.

Importantly, “Recent Ancestry in the Americas” should be complementary to your Ancestry Composition percentages, and both results together should help you build a more complete understanding of your ancestry and how it may have changed over time.
A snapshot of genetic diversity in the Caribbean and Latin America
The Ancestry Composition breakdown of 23andMe customers from countries in the Caribbean typically reflects southern European, West African, or Native American ancestry. While customers from Spanish-speaking islands generally have a combination of all three of these ancestries, customers from Haiti, Jamaica, Grenada, or other smaller islands have little Indigenous heritage and a much higher proportion of West African ancestry. This is a result of the large numbers of enslaved Africans transported to the Caribbean over the course of nearly four centuries.Did you know?
Native Caribbean ancestry — primarily from the Indigenous Taíino peoples who once called these islands home — is still found in Puerto Rico, Cuba, and the Dominican Republic (former colonies of Spain) but is almost completely absent on the islands formerly claimed by Britain and France. On average, Puerto Ricans have around 12% of this Taíno ancestry, but over 60 percent of their maternal-line ancestry is of Taíno origin.Mexico & Central America
Customers from Mexico & Central America often have a combination of Native American, southern European, and West African ancestry in their DNA, though the breakdown varies throughout the region. Native American ancestry generally reaches its highest levels in Mexico, El Salvador, and Guatemala, while West African ancestry ranges from an average of 2 percent in Mexico to over 40 percent in Belize. Today, most 23andMe customers with Mexican or Central American ancestry have at least 1 percent African DNA, reflecting admixture that occurred many generations ago, early in the Translatlantic Slave trade.
23andMe customers from Ecuador or Peru typically have over 45 percent Native American ancestry, while customers from Brazil, Argentina, and Uruguay tend to have less than 10 percent of this genetic heritage. Indigenous ancestry remains highest where there were once large agricultural civilizations, though many factors likely contributed to the variable rates of Native American ancestry across the continent.
What about African ancestry? For 23andMe customers from Colombia or Venezuela, the most common African ancestry is Senegambian & Guinean, while customers from Brazil typically have more Angolan & Congolese ancestry. Between the 17th and 19th centuries, Portugal transported as many as five million enslaved Africans to Brazil, primarily from Angola and the Congo river basin. Today, an African genetic signature peaks among 23andMe customers with roots in the east Brazilian state of Bahia.
Did you know?
23andMe customers from Guyana and Suriname—former British and Dutch colonies, respectively—have particularly high levels of African genetic heritage, and the region is often considered to be more culturally and politically aligned with the Caribbean than it is with the rest of South America.If you want to learn more about the genetic history and diversity of these regions, check out the educational modules near the top of each new report!

Using the last three links for Caribbean Report, Mexican and Central American Report, and South American Report, the reports indicate I did not have any ancestors from those areas.
